What produces phenotypes of both homozygotes in the heterozygote?

When phenotypes of both homozygotes are produced in the heterozygote?

Chapter 12 vocabulary

A B
codominant alleles phenotypes of both homozygotes are prod. in the heterozygote.
completely dominant alleles phenotypes of both heterozygous & homozygous dom indiv. have same phenotype.

What produces the phenotype of a heterozygote?

Two different alleles at a locus are responsible for different phenotypes, and both alleles affect the phenotype of the heterozygote.

When the phenotype of the heterozygote is in between the phenotypes of both homozygotes it is called?

This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.

What alleles that are both expressed in a heterozygote?

If both alleles are dominant, it is called codominance?. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles.

Which type of dominance occurs when the heterozygote expresses the phenotypes of both homozygotes simultaneously?

Codominance. As opposed to partial dominance, codominance occurs when the phenotypes of both parents are simultaneously expressed in the same offspring organism.

When both phenotypes are present in the heterozygote showing both traits at once it is known as?

With codominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype in which both of the parental traits appear together.

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

Incomplete dominance is when traits are inherited in a pattern where the phenotype of heterozygous individuals is intermediate between those of two homozygotes.

When both alleles are expressed equally in the phenotype of the heterozygotes?

Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote. The red and white flower in the figure has codominant alleles for red petals and white petals. Codominance.

How does genotype determine phenotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

When both the alleles dominant and recessive are equally expressed in the hybrid The phenomenon is known as?

Codominance pertains to the genetic phenomenon in which gene products from the two alleles in a heterozygote are produced in roughly equal amount, where gene products refer to either different transcripts from the two alleles, different proteins from cellular processing of the transcripts, or different metabolites …

When both traits are exhibited in the phenotype It is said that the alleles display?

Codominance refers to the dominance in which the two alleles or traits of the genotypes (of both homozygotes) are expressed together in offspring (phenotype).
