Consider a hypothetical plant. There are two genes that dictate how the flower will smell. These two genes are located ON THE SAME CHROMOSOME. Gene B has two alleles: The dominant allele (B) encodes for "banana" smell. The recessive allele (b) encodes for "strawberry" smell. The other gene that influences smell (gene C) also has two alleles. The dominant allele (C) encodes for "chocolate" smell, and the recessive allele (c) encodes for "vanilla" smell. Now, consider a cross. The first individual is homozygous for both of the recessive alleles. The second individual has a chromosome with "B" and "C" alleles, and a chromosome with "b" and "c" alleles. Assume that no crossing over happens during meiosis. What proportion of the offspring will produce flowers that smell like vanilla strawberries?
