The grey symbols are people with a disease that is caused by a sex-linked gene. The red symbols are not sick. 7 and 8 are having a child, 11. 11 turns out to be a girl. What is the chance she has the disease?

In Drosophila (fruit flies) there is a recessive allele that causes veinless wings. This gene is located on the X-chromosome. A female with veinless wings is crossed with a male with normal wings. The F1 offspring that come from this cross and used to cross with each other to form the F2 generation. Which percentage of the F2 females will have veinless wings?

Charcot–Marie–Tooth disease (CMT)causes motor and sensory neuropathies of the peripheral nervous system.
1. What is the inheritance pattern shown?
2. Provide at least one piece of evidence for your claim.
3. The dashed line represents a possible union. Discuss the probability that such a union would result in a child with CMT.
