Answer:
The parental genotype (P) will be : BB for the black rooster, bb for the white hen.
The F genotype will be : Bb
The F phenotype will be : all black offspring
Phenotype possible in this inheritance pattern will be black or white.
Explanation:
To depict the outcomes of a cross between a purebred black rooster and a purebred white hen, the following punnet square can be made:
b b
B Bb Bb
B Bb Bb
<u>As the outcomes of the punnet square depict, all of the offsprings will be black as it is the dominant trait. The recessive trait will become suppressed. </u>
<u>However, all of the offsprings will be heterozygous for the trait, Bb. </u>
