Afarmer raises black and white chickens. to his surprise, when the first generation of eggs hatch all the chickens are black with white speckles throughout their feathers. what should the farmer expect when the eggs laid after interbreeding the speckled chickens hatch?
all the offspring will be speckled.
75% of the offspring will be speckled, and 25% will be black.
50% of the offspring will be speckled, 25% will be black, and 25% will be white.
50% of the offspring will be black and 50% of the offspring will be white.

Option C

Explanation:

Let the allele for black color be "B"

and the allele for white color be "b"

Since after F1 generation all the offspring have black  body with white speckles throughout their feathers.

Thus the allele for black and white show co dominance.

Genotype of parent after F1 generation would be Bb for speckled chickens

Cross between two specked adults will produce -

Bb x Bb

BB, Bb, Bb, bb

Out of four offspring 1 is black (BB), 1 is white (bb) and two are speckled (Bb)

Thus 50% of the offspring will be speckled, 25% will be black, and 25% will be white.

Option C is correct
