The document discusses the inheritance of sex-linked traits, particularly focusing on eye color in fruit flies. It explains that females have two X chromosomes while males have one X and one Y chromosome, making males more likely to express recessive traits. The activity involves identifying the sexes and eye colors of fruit flies based on specific genotypes, as well as determining potential genotypes correlating to observed traits.

- 1. Up until this point you know that genes are located on specific chromosomes at specific locations. However, there are many genes that are linked with the sex chromosomes, more specifically the X chromosome because it is larger. Females have two X s ( XX ) while males ( X Y ) only have the one X with their one Y . Due to this difference males are more likely to show a recessive sex-linked trait. For this activity you will be looking at the sex linked genes of eye color in fruit flies to better understand how sex linked genes determine phenotypes. In fruit flies, eye color is a sex linked trait and the red eye color is dominant to the white eye color. 1. With that in mind, identify the sexes and eye colors of the flies based upon the following genotypes. 2. Identify a potential genotypes of these flies with the given traits:
