In mice, the allele for black fur is dominant to the allele for brown fur. a male homozygous black mouse is crossed with a femal
Darina [25.2K]
B- black allele;
b- brown allele;

The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb

The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
 1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being  brown homozygote- bb- 25%
answer: 25%+25%=50%  are homozygotes
