Problem
In rabbits, there is a dominant gene "T" and a recessive allele "t" for shorts ears. at another gene locus there are alleles for "B" black coat and "W" for white coat. Neither is dominant and BW produces a gray coat. these two alleles pair assort independently. if gray rabbit that is heterozygous at the gene locus controlling ear length is mated with a white rabbit that is also heterzygous at the gene locus controlling ear length what is proportion of the long-eared offspring will be homozygous for that trait.
