Answer:
n order to create a Punnett square, we need to list the possible gametes (sex cells) that each parent can contribute to their offspring. Since Michael and Danielle both have the Bb genotype, they can each contribute a B or a b allele to their offspring.
Possible gametes for Michael: B or b
Possible gametes for Danielle: B or b
Using these gametes, we can create a Punnett square to show the possible genotypes of their offspring:
B b
B BB Bb
b Bb bb
From the Punnett square, we can see that there are four possible combinations of alleles for their offspring: BB, Bb, Bb, and bb.
BB: This offspring would have two dominant B alleles, resulting in dark brown skin.
Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.
Bb: This offspring would have one dominant B allele and one recessive b allele, resulting in tan skin.
bb: This offspring would have two recessive b alleles, resulting in light skin.
Therefore, it is possible for Michael and Danielle to have two babies with different skin colors, one with dark brown skin and the other with tan skin, due to the combination of their different alleles in their offspring.
