Question

The white Leghorn breed of chickens is homozygous for the dominant allele C, which produces pigmented feathers. However this breed is also homozygous for the dominant allele “I”, an independently assorting gene that inhibits coloration of the feathers. Consequently, Leghorn chickens have white feathers. The white Wyandotte breed of chickens have neither allele for color nor the inhibitor of color; it is therefore genotype ccii.

What is the phenotype of the F1 generation of Leghorn by Wyandottes?

What are the F2 phenotypes and proportions expected from this cross?

This is an example of what sort of gene interaction?

Explanation / Answer

CcIi is the phenotype of the F1 generation of Leghorn by Wyandottes.

we can see here in F1 generation there are two heterozygous so they produce 4 types of gametes which are CI, Ci, cI, ci. by punnet square we can get the 9:3:3:1.

its a multigene interaction
