The answer is C. homozygous, phenotype, genotype, heterozygous
Answer:
50%
Explanation:
If black is dominant to white color and crossing with parents produced some progeny which were black and a white progeny then it simply indicates that parents were heterozygous for the trait even if phenotypically they appeared black. A cross between parents is shown as under:
Parents
Bb x Bb
Progeny: BB Bb Bb bb
BB and Bb allelic combinations produced a black mice while bb combinations produced white mice.
Now the subsequent cross between one of the parents and white off spring is shown as under:
Bb x bb
Progeny: Bb Bb bb bb
It is clear from the cross above that the progeny with Bb allelic combinations will be black while with bb combinations they will be white. 2 out of the 4 progeny are genotypically bb that means they are white i.e. 50% progeny are white.
