What phenotype does Codominance result in?

In codominance, the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive. As for the incomplete dominance definition, this form of inheritance occurs when the phenotype is intermediate to the phenotype of the parents.

Does codominance create a new phenotype?

In codominance, both alleles are expressed together in the offspring. Unlike incomplete dominance, where the two parent phenotypes are blended together into a new phenotype, in codominance, both parent phenotypes show up together on the offspring. … The most common example of codominance is the AB blood type.

What resulted from codominance?

Codominance suggests that both phenotypes are dominant, but cannot be expressed at the same time. The result of codominance would be regions of dominant red expression and regions of dominant white expression, resulting in spots rather than blending.

What is the phenotype and genotype of codominance?

In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Which of the following phenotypes is an example of codominance?

An example of codominance occurs in the human ABO blood group system. Many blood proteins contribute to blood type (Stratton, 1952), and the ABO protein system in particular defines which types of blood you can receive in a transfusion.

How many phenotypes are possible in codominance?

Two phenotypes are possible in codominance.

What is the phenotypic and genotypic ratios in incomplete dominance and codominance?

In incomplete dominance and co-dominance, genotypic and phenotypic ratios are identical.

How do codominant genes affect the phenotype of an animal?

Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.

What does Codominance mean in genetics quizlet?

Codominance. A condition in which neither of two alleles of a gene is dominant or recessive. codominant alleles. Pairs of alleles that both affect the phenotype when present in a heterozygote. You just studied 5 terms!

Which is an example of Codominance quizlet?

Codominance is the type of inheritance that occurs when a heterozygote displays both alleles equally. An example would be AB blood type in humans or a red and white striped flower. … An example would be a pink flower.

Which type of dominance occurs when the heterozygote has the same phenotype as one of the homozygotes?

Incomplete dominance and codominance

The results of Mendel established that genes can exist in two alternate forms (i.e., one dominant and other recessive). The dominant allele expresses the same phenotypic effect in heterozygotes as in homozygotes (i.e., Aa or AA are phenotypically similar).

What is the phenotype of a heterozygous four o’clock flower?

INCOMPLETE DOMINANCE: In Four O’Clock plants RED FLOWERS (R) are INCOMPLETELY DOMINANT over white (r) flowers. Heterozygous plants show a BLENDED INTERMEDIATE phenotype of PINK flowers.

In which of the following incomplete dominance is observed?

Example: Incomplete dominance is seen between red and white snapdragon plants in cross-pollination experiments. In the recessive allele that produces the white colour (r), the allele that produces the red colour (R) is not fully expressed.

Which of the following is a phenotype?

A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype.
