Answer:
50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
Explanation:
The black chickens are the dominant allele and the white chicken are the recessive allele. Since the black chicken is dominant, Let the genotype of the black chickens be (BB) and the genotype of the white chicken be (ww).
If the Black and white chicken are cross bred and the eggs hatched are black with white speckles, i.e (Bw). The genotype of all the hatched chickens would be (Bw). Where Bw is speckled chicken.
If the hatched chicken with genotype (Bw) are interbred, the resulting hatched chickens genotype would be BB, Bw, Bw and ww for four offsprings. This shows that 50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
