In guinea pigs, black fur is dominant and white fur is recessive. A homozygous dominant black guinea pig is bred with a homozygous recessive white guinea pig. The dominant allele is represented by F, and the recessive allele is represented by f. Create a Punnett Square and answer the following question: What is the probability of having white fur guinea pigs with this combination

The following cross represents the parent genotype for the offspring whose phenotype is to be determined.

Homozygous dominant black guinea pig FF

X

Homozygous recessive white guinea pig ff

The probability of having white fur guinea pig offspring is zero in the first generation because all of the offspring will be Ff, which is the genotype for black fur.

Punnett Square:

F F

f Ff Ff

f Ff Ff

Hope that answers the question, have a great day!
