The trait of medium-sized leaves in iris is determined by the genetic condition PP’. Plants with large leaves are PP, while plants with small leaves are P’P’. A cross is made between two plants each with medium-sized leaves. They produce 80 seedlings. Of the 80 seedlings produced from this cross, how many would you expect to have large leaves?

Based on these data, sepia eyes and ebony body are _________ to the wild type trait.

Sepia eyes (sp) and ebony body (eb) are two fruit fly mutations. You cross a wild type female fly with a sepia-eyed, ebony bodied male fly. All of the resulting offspring were phenotypically wild type. Offspring of the F2 generation had the following phenotypes: Sex Phenotype Number female Wild type 75 female Sepia/ebony 25 male Wild type 75 male Sepia/ebony 25   How were you able to determine your answer to the previous question?
