Question

1. You are working with a rare species of beetle which has both green and blue morphs. Upon studies of this beetle, you find that the blue morph (B) is dominant over the green morph (b). You discover that there are actually two different types of antennae as well, a serrate antennae (S, looks like a saw blade or a bread knife), which is dominant over the recessive filamentous antennae (s). a. A BbSs individual mates with a bbSs individual. Use a branch diagram to predict the expected phenotype frequencies? (1 pts) b. You are working on these beetles with a partner, and they forget to tell you what parents they cross to get a set of offspring. You, however, remember how to calculate genotypes from the phenotypes of offspring. Below are the numbers of offspring from this cross. What is a possible set of genotypes for the parents? (1 pts) 722-blue with filamentous antennae 735-blue with serrate antennae 238-green with filamentous antennae 248-green with serrate antennae
