Question

If you cross two heterozygous gray mice , what are the genotypes and genotypic percentages of the offspring ?

Answer 1

During the first years after the rediscovery of Mendel's laws, a number of experiments were performed that gave results that at first glance did not coincide with the laws. In 1904, a cross was made between a yellow-coated mouse and a mouse with a gray coat. The gray- coated mouse was extensively inbred and therefore was considered to be pure bred.
