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?

The events of the last four questions will continue until what happens?

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

When homologous chromosomes separate during meiosis, all the paternal chromosomes go into one daughter cell and all the maternal chromosomes go into another daughter cell.

Duplication of DNA occurs: 

(Still putting the events of transcription in the correct order.) Fourth…  

During which stage of meiosis does crossing over occur? 

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. How would you describe the genotype of the plants with medium-sized leaves?

The second tRNA to attach to the mRNA will be carrying the amino acid:

Regulating gene expression allows a cell to:
