Answer 1

Answer:

Using a Punnett square, work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus. In guinea pigs, heterozygous male with black coat colour (Bb) is crossed with the female having white coat colour (bb).

Hope this answer is helpful for u.

Answer 2

Answer:

If B is dominant over b, a cross between a homozygous female (bb) and a heterozygous male (Bb). The male will produce two types of gametes, B and b, while the female will produce only one kind of gamete, b. The genotypic and phenotypic ratio in the progenies of F1 generation will be same i.e., 1:1.
