Answer:
Option C, Black and speckled
Step-by-step explanation:
In this case a hen with speckled feathers is a species with a co dominant phenotype where both the traits of black and white feathers are present individually without blending with each other.
Let the genotype for black feathered species be BB
The genotype for white feathered species be WW
The genotype for speckled feathered species be BW
BB * BW
BB, BW, BB, BW
The offspring will have both Black and speckled species.
Option C is correct
