Question

For the following questions, create a Punnett square. Be sure to show the genotypes, phenotypes, and percentages for each cross.

Answer 1

From the Punnett square, the genotype of the offspring produced is:

• 1 h0moxygous Black,BB; 2 two heterozygous black = Bb, Bb; and 1 h0moxygous white, bb; guinea pigs

The phenotype of the offspring will be:

• Three Black fur guinea pigs and one White fur guinea pig.

What are phenotypes and genotypes?

Genotypes are the sum total of all the genes that code for a particular trait present in an organism.

The genotype is the sum of all the alleles for a gene in an organism.

Phenotype refers to the physical features of an organism as a result of the genotype of that organism.

Considering the cross between two heterozygous black guinea pigs:

black fur is dominant over white fur in guinea pigs

Let the allele for black fur be B and the allele for white fur be b

The genotype of the heterozygous black guinea pigs = Bb

The cross between the parents is as follows:

Bb * Bb

Using a Punnett square, the genotype of the offspring produced will be:

BB, Bb, Bb, bb

The phenotype of the offspring will be in the ratio 3 Blacks to 1 White guinea pig
