Erminette chickens (bw) display codominance. black is dominance. white is dominant. erminette chickens are speckled with black and white feathers. what is the phenotypic ratio of the offspring if two erminette chickens are crossed?

1 BB: 2BW: 1WW

Explanation:

The probability of getting a black chicken is 1/4, that of black-white is 1/2 and that of a white chicken is 1/4. In codominance, there is intermediate expression in the phenotype.

       B                W

B    BB              BW

W   BW             WW

The phenotypic ratio is 1 black: 2 black-white: 1 white

the answer is

c. parental

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
