Question

step 1: predict the offspring for a cross of true-breeding lineages (bbee × bbee)
the punnett square is for a test cross of two mice that were purebred for two different traits. what will their offspring be? fill in the white boxes of the punnett square with all possible offspring genotypes

Explanation:

Step1: Analyze the gametes

The pure - bred parent \(BBEE\) can only produce gametes with the genotype \(BE\). The pure - bred parent \(bbee\) can only produce gametes with the genotype \(be\).

Step2: Use the Punnett square principle

When filling in the Punnett square, we combine the gametes from each parent. For the box where the gamete \(BE\) (from \(BBEE\)) and \(be\) (from \(bbee\)) combine, we use the rule of combining alleles. For the \(B/b\) gene, \(B\) (from \(BE\)) combines with \(b\) (from \(be\)) to give \(Bb\). For the \(E/e\) gene, \(E\) (from \(BE\)) combines with \(e\) (from \(be\)) to give \(Ee\). So the genotype is \(BbEe\).

Answer:

\(BbEe\)
