Concept

Problem: In a species of butterfly, the blue-wing allele (B) is dominant to the yellow wing allele (b) and the allele for long antennae (L) is dominant to the allele for short antennae (l). If a butterfly is homozygous recessive for antennal length, its wings always end up being blue. If one butterfly is Bbll and a second butterfly is BbLl, what is the chance that they will produce offspring that have short antennae and blue wings?a. zerob. 3/8c. 1/2d. 3/4e. 1/1
