A homozygous dominant brown mouse is crossed with a heterozygous mouse. Tan is the recessive color.

1/2 will be homozygous dominant brown and the other half will be heterozygous for brown

If a purebred dominant brown mouse is crossed with a heterozygous **mouse **whose color is tan , then possible **offspring **are half brown as they are dominant , and the other half are heterozygous for tan, but all are brown.
What are recessive and Punnett squares?
Punnett squares is used to determine the possible outcomes of a cross between two individuals with known genotypes. The Punnett square is a grid that shows all the possible combinations of **gametes **(sperm and egg cells) that can be produced by each parent, and the resulting offspring genotypes. In the case of this problem, one parent is purebred **dominant **for the brown color gene (BB) and the other parent is heterozygous for the same gene (Bb). So half of the offsprings will be Bb and half will be BB.
Hence, the possible **offspring **are half brown as they are dominant , and the other half are heterozygous for tan, but all are brown .

When a homozygous dominant brown mouse (BB) is crossed with a heterozygous brown mouse (Bb), all the resulting offspring will be brown (100% brown phenotype). This occurs because both genotypes (BB and Bb) include at least one dominant allele for brown color. Thus, no tan mice offspring will be produced in this cross.
