In mice, gray fur (G) is dominant to white fur (g). Consider the following cross between two mice. The diagram below shows the Punnett square. Gg x Gg. What is the genotype of the offspring indicated by box 1? GG White Gg gg

To determine the genotype of the offspring indicated by box 1 in the Punnett square for the cross Gg x Gg, we need to look at the possible combinations of alleles that can occur.<br /><br />In this case, the Punnett square shows the following combinations:<br /><br />- Box 1: GG<br />- Box 2: Gg<br />- Box 3: Gg<br />- Box 4: gg<br /><br />Therefore, the genotype of the offspring indicated by box 1 is GG.
