Solution :-

In the case of coat colour of guinea pigs, when heterozygous male guinea pigs (Bb) with black coat are crossed with homozygous female guinea pigs with white coat (bb), we can see that the male produces two types of gametes B and b while female produces one kind of gamete b. Through Punnett square we see genotypic and phenotypic ratio in F1 generation is same , i.e., 1:1
