When phenotypes of both homozygotes are produced in the heterozygote?

Question Answer
when the phenotype of the heterozygote differs from the phenotypes of both homozygotes Incomplete dominance
In the heterozygous condition, only one allele (dominant) is expressed. Mendelian concept
Heterozygote expresses both alleles/both phenotypes. Codominance

What produces phenotypes of both homozygotes in the heterozygote?

Codominance is both phenotypes of both homozygous to be produced in heterozgous individuals (both alleles are expressed equally). Incomplete dominance when both heterozygous and homozygous have the same phenotype.

When the heterozygote has a phenotype intermediate between the two homozygotes this is called?

When the heterozygous phenotype is intermediate between the two homozygous phenotypes, the pattern of inheritance is called incomplete dominance.

What pattern of inheritance results when the phenotype of a heterozygote is intermediate between both homozygotes?

Incomplete dominance pertains to the genetic phenomenon in which the distinct gene products from the two codominant alleles in a heterozygote blend to form a phenotype intermediate between those of the two homozygotes.

What determines phenotype in a heterozygote?

Two different alleles at a locus are responsible for different phenotypes, and both alleles affect the phenotype of the heterozygote. … Both the A and B alleles contribute to the phenotype of the heterozygote. Thus the alleles A and B are said to be co-dominant.

What is phenotype example?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Is AA heterozygous or homozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

Is true breeding always homozygous?

A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for every trait. … With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate.

When a heterozygote shows an intermediate phenotype this is called?

incomplete dominance. exhibited when the heterozygote has an intermediate phenotype between that of either homozygote. incomplete penetrance. an individual who obtains a dominant allele will not necessarily display the dominant phenotype.

What would be the phenotypes of the offspring?

The phenotype is the trait those genes express. … Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene. This means there is a 100% chance of the offspring having brown eyes, or being BB. It’s important to note here that each box represents a possible offspring.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
