Answer:
Hand = 75%
No hand = 25%
Step-by-step explanation:
It's the same thing as last time. Since 3 of them are heterozygous and have 1 dominant allele, they have the dominant trait. And since one of them only has recessive alleles then it should have the recessive traits.
So the hand should have 75% and no hand has 25%.
