In Rabbits, There Is a Gene That Controls Ear Length

In rabbits, there is a gene that controls ear length, with a dominant allele "T" for long ears and a recessive allele "t" for short ears.At another gene locus, there are alleles "B" for black coat and "W" for white coat.Neither the B or W allele is dominant, and BW produces a gray coat.These two allele pairs assort independently.If a gray rabbit that is heterozygous at the gene locus controlling ear length is mated with a white rabbit that is also heterozygous at the gene locus controlling ear length, what is the probability that their first offspring will be gray with long ears?

A) 1/16
B) 3/16
C) 1/8
D) 3/8
