Answer:

All of the genotypes for question one are possible. for question 2, the genotype of offspring 2 is Dd.

Explanation:

The chart shows that there can be a combination of genes DD, Dd, and dd (D being the dominant trait, d the recessive). there's a one in four chance of blindness for the dog. by reading the rows and columns of the chart, you can determine which genes the dog will have.

1.Since both of the parents are heterozygous the offspring can have all three genotype possiblities: DD Dd and dd

2.The genotype of offspring is the combination of the alleles D and d:Dd
