In D. melanogaster, cherub wings (ch), black body (b), and cinnabar eyes (cn) result from recessive alleles that are all located on chromosome 2. A homozygous wild-type fly was mated with a cherub, black, cinnabar fly, and the resulting F, females were test-crossed with cherub, black, cinnabar males. The following progeny were produced by the testcross: ch b* сп 105 ch* b* cn* 750 ch* 40 cn ch* b+ сп 4 ch cn 753 ch b+ cn* 41 ch* cn* 102 ch сп Total 1800

Crime Scene Investigation

A crime scene refers to a place where a crime has occurred. The purpose of crime scene investigation (CSI) is to analyze the complete scene and catch the culprit based on the pieces of evidence collected from the place of crime. The people involved in this process are referred to as crime scene investigators.
