Question

2. Codominance: Diricrawls are plump, fluffy-feathered, flightless birds. Feather color

is co-dominant; FF have pink feathers, PP have purple feathers and mottled diriclaws (FP)
have both pink and purple feathers. Pink feathered diricrawls are very rare and prized by
collectors. If you breed a pink diriclaw with a mottled diricrawls, what percentage of their
offspring will be pink feathered? (show all of your work and use a Punnett square).

Answer 1

The correct answer is - 50% or 1/2.

Step-by-step explanation:

In codominance both alleles express their traits and blend to make new traits, there is no dominance or recessive pattern found. In this question, there is FF have pink feathers, PP has purple feathers and mottled diriclaws (FP). Then a cross between pink feathers and mottled diriclaws would produce offspring:

F F

F FF FF

P FP FP

Here two out of four have pink feathers. That is 50%
