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

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
