A chicken with black feathers (BB) is crossed with a chicken with white feathers (WW). The offspring have black and white feathers.
What is the genotype of the offspring?
1.) BW
2.) BW
3.) BW
4.) BW
This is ✔ codominance because there are two ✔ dominant traits.
What is the genotype of the offspring? Explain incomplete dominance, using snapdragon flowers as an example.
Sample response:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.
