Question

step 3: predict the offspring of a dihybrid cross (bbee × bbee)
the punnett square shows a text cross of mice that are heterozygous for both traits. what will their offspring be? fill in the white boxes of the punnett square with all possible offspring genotypes.
a female mouse that is heterozygous for both genes (bbee)
a male mouse that is heterozygous for both genes (bbee)

Explanation:

Step1: Combine alleles

For the cell with row - label \(Be\) and column - label \(BE\), we combine the alleles from the row (\(Be\)) and the column (\(BE\)).
We use the rule of combining alleles in a Punnett square: for each gene locus, we take one allele from the row - parent and one from the column - parent.
For the \(B/b\) locus: \(B\times B = B\). For the \(E/e\) locus: \(e\times E=Ee\).

Answer:

\(BBEe\)
