In Rabbits,there Is a Gene That Controls Ear Length,with a Dominant

question 2

Multiple Choice

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 proportion of the long-eared offspring will be homozygous for the long-eared trait?

• A)1/8
