Question

A punnett square is shown below. Read the question and click on the area of the punnett square that was set-up

incorrectly.
Brown fur is dominant to white fur in a species of rabbit and is represented with th
alleles "B" and “b”. What are the resulting percentages of genotypes of a crossing between a homozygous dominant parent and a heterozygous parent?

Answer 1

The resulting percentages of genotypes of a crossing between a homozygous dominant parent and a heterozygous parent are 50% BB and 50% Bb.

Step-by-step explanation:

The resulting percentages of genotypes of a crossing between a homozygous dominant parent (BB) and a heterozygous parent (Bb) can be determined using a Punnett square.

In this case, the Punnett square should have the genotypes BB and Bb along the top and sides, respectively. The resulting percentages of genotypes will be 50% BB and 50% Bb, as shown in the Punnett square.

Answer 2

50% BB and 50% Bb are the resultant genotype percentages of a crossover between a homozygous dominant parent and a heterozygous parent.

A Punnett square may be used to calculate the percentages of genotypes that occur from a crossover between a homozygous dominant parent (BB) and a heterozygous parent (Bb).

The genotypes BB and Bb should, in this instance, be arranged at the top and sides of the Punnett square, respectively. The genotype percentages that result will be 50% BB and 50% Bb, as the Punnett square illustrates.

50% BB and 50% Bb are the resultant genotype percentages of a crossover between a homozygous dominant parent and a heterozygous parent.
