Amoeba Sisters Video SELECT Recap: Incomplete Dominance, Codominance,
Polygenic Traits, and Epistasis (Non-Mendelian Inheritance)
AP
Codominance can be observed in some breeds of chicken. Black chickens can result from BB alleles. White chickens can
result from WW alleles. A chicken with alleles BW can be speckled with black and white.
8. Show a Punnett square with a Mendelian cross between two chickens that pre BW x BW.
9. According to your work, complete the following phenotype ratio:

Incomplete dominance can be observed in snapdragons. Snapdragon flowers
that have two RR alleles have a red phenotype. Snapdragon flowers with a rr
have a white phenotype. Snapdragon flowers that are Rr are pink.
11. Fill in the two Punnett squares in diagram at right.
12. This is a non-Mendelian trait, but how could this be different if the trait
was Mendelian?
