A phenotype is a physical characteristic of an organism, such as a tall pea plant. An organism's genotype is the specific gene combination that makes up a characteristic using Punnett Square. For example, a tall pea plant might have a genotype of TT or Tt, whereas a small pea plant may have a genotype of tt. Note: In this case "T" is dominant and "t" is recessive. Asked in Biology, Genetics If homozygous tall pea plant and a homozygous short pea plant are crossed?

TT x tt all offspring will be Tt heterozygous genotype and tall phenotype. Asked in Biology, Genetics Does a pea plant with the genotype TT have the smae phenotype as a pea plant with genotype tt? TT is the dominant phenotype what ever it may be and tt is the recessive phenotype what ever that may be. So say T is the allele for Tall plants, t is the allele for short plants.

TT would be show the tall phenotype while tt would show the short phenotype.

if a pea plant has the two alleles yy what is its genotype

If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t short plants. Asked in Science, Genetics If an organism expresses a recessive phenotype can you tell genotype?Played 0 times.

Unanswered Questions. If a pea plant has the two alleles yy. Wiki User Related Questions Asked in Genetics, Biology How can you tell whether an allele is dominant or recessive?

The dominant allele is the one that corresponds to the phenotype shown while the recessive allele is the one that corresponds to the alternate phenotype not shown by the organism. In pea plants from Gregor Mendel's famous experimentsthe "tall" allele was dominant over the "short" allele, so a pea plant with one or two "tall" alleles was a tall pea plant and a pea plant with two "short" alleles was a short pea plant. Asked in Genetics, Gregor Mendel What happens in Mendel's experiments when a pea plant received two different alleles for the same trait?

Unless the alleles are codominate which Mendel did not have in pea plantsone will be dominate and will be what you see phenotype and one will be recessive and you will not see it. Asked in Science, Biology In pea plants individuals that are Pp for the alleles that code for flower color will have purple flowers.

What is the phenotype? In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. Asked in Biology, Genetics What is the phenotype of a flower in a pea plant that is homozygous recessive? It will have the recessive phenotype. Asked in Biology, Genetics What is the phenotype of a flower in a pea plant that is homozygous dominant? It will have the dominant phenotype. Asked in Botany or Plant Biology, Genetics What can a yellow pea plant and a green pea plant produce?

Asked in Genetics How does a recessive or dominant allele effect hereditary influence? The traits inherited depends upon the alleles that have been passed on from the father and mother. The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed. For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele.

TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.

Solving Genetics Problems

Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait. In this case the dominant allele masks the recessive allele and the pea plant is still tall.

For a recessive trait to show up there should be a pair of recessive alleles. Asked in Genetics What is the combination alleles in purebred short of pea plant?

Two alleles for tall stems. Asked in Biology What is a Homozygous dominant pea plant?

if a pea plant has the two alleles yy what is its genotype

A pure pea plant with same two dominant alleles for a trait eg. TT for tall plant. Asked in Genetics Pea plant shows a recessive phenotype?The difference: Phenotype is the expressed dominant allele "Y" for green only, and not "y" for yellow. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles.

One allele codes for purple flowers and is represented by the uppercase letter F, whereas the second codes for white flowers and is represented by the lowercase letter f. A varied population of sweet pea plants could therefore feature three possible genotypes at this locus: FF, Ff, or ff. Each plant's genotype contributes to its phenotype, which, in this case, is the outward appearance of its flowers.

A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.

The process of determining a genotype is called genotyping. The phenotype is what you see, the genotype is the alleles. There are two kinds of alleles: dominant and recessive.

Take, for example, the colour of the pea casing. The dominant colour is yellow, so we'll represent it by Y, and recessive is g. If the plant is yellow, its phenotype is yellow. However, its genotype could be YY, or Yg - since the yellow is dominant, if the Y allele is present, the phenotype is automatically yellow.

However, if the plant is green, its genotype must be gg, as the green colour is recessive and both alleles must be g in order to appear green. The same applies to whether the peas are wrinkly or not wrinkly being recessivewhether the flowers are white or violet, how tall the plant is, and other characteristics.

Genotype: A set of genes of an organism, i. Further reading: Genotype "In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. Still have questions?

Get your answers by asking now.If a homozygous recessive pea plant is crossed with a heterozygous pea plant, what ratio of dominant to recessive phenotypes should occur in the offspring?

Do a punnett square with Tt x tt. The phenotype of the two Tt would be tall, and the phenotype of the two tt would be short. Hybrids are organisms that result from cross-breeding, and usually have different copies of the same genes.

Dominant factors are genes that show up even if only one copy is that gene. Recessive factors are ones that show up only if all copies are the same. However, some genes do cause mixing, which would cause medium height. If you haven't discussed mixing which is likelythen the answer is A. It is used to figure out how the different genes can combine in the offspring. Mitosis is when one cell divides and becomes two; both are identical genetically.

Meiosis is when one cell divides and becomes four cells that only have half of the chromosomes of the original cell; it is involved in sexual reproduction. Homozygous means having the same copy of a certain gene. Heterozygous means having two different copies of that gene.

A heterozygous genotype has two different alleles. For example, a tall pea plant that is heterozygous would have the genotype Tt, with the T representing the tall allele, and the t representing the short allele. A hybrid is heterozygous, and a pea plant that is a hybrid for stem length would have the heterozygous genotype Tt. Asked in Genetics What is the combination alleles in purebred short of pea plant?

Two alleles for tall stems. Asked in Genetics What are the genotypes of a heterozygous tall pea plant? The genotype is heterzygous, meaning that there are two different alleles. If you want to use letters to represent the tall and short alleles, you could use T for tall capital letter indicates a dominant alleleand t for short lowercase letter indicates a recessive allele. So the heterozygous genotype for a tall pea plant could be indicated by Tt.

Asked in Biology What is a Homozygous dominant pea plant? A pure pea plant with same two dominant alleles for a trait eg. TT for tall plant. Asked in Genetics What genotype has different alleles? The genotype that has two different alleles is heterozygous.

Asked in Genetics, Biology How can you tell whether an allele is dominant or recessive? The dominant allele is the one that corresponds to the phenotype shown while the recessive allele is the one that corresponds to the alternate phenotype not shown by the organism. In pea plants from Gregor Mendel's famous experimentsthe "tall" allele was dominant over the "short" allele, so a pea plant with one or two "tall" alleles was a tall pea plant and a pea plant with two "short" alleles was a short pea plant.

A genotype consisting of two different alleles is a heterozygote. Asked in Microbiology, Genetics Two alleles for tall stems? If the letter T represents the dominant allele for tall stems in pea plants, the genotype that has two tall alleles is homozygous dominant, and is written TT.

Asked in Genetics How would you describe the alleles in a heterozygous genotype? A heterozygous genotype includes two different alleles. Asked in Biology, Genetics A pea plant that has two different alleles for the same trait is said to be what? Any organism which has two different alleles for the same trait is described as heterozygous.
