Feather Color in Chickens Is the Result of an Incompletely

question 20

Essay

Feather color in chickens is the result of an incompletely dominant gene. The gene responsible for black feathers (B) when homozygous results in a muted color called "Andalusian blue" if combined with an allele for white feathers (b). When the white allele occurs in homozygous conditions, a white phenotype results. A gene affecting comb shape (R), which results in a comb called a "rose" comb, is completely dominant over (r), which in homozygous conditions results in a comb called "single." A mating between a black single rooster and white rose hen results in a number of chicks, all of which have identical phenotypes.
-Use a Punnett square to demonstrate a cross between two of the F₁ offspring.What are the phenotypes and ratios that occur?
