Hypertrichosis is a genetic mutation, based on the DNA from Danny and his normal brother, what type of mutation do you think that Danny has? Explain why you think so.

Answer and Explanation:

Hypertrichosis is an abnormal hair growth over the body. There are two types of hypertrichosis, such as localized hypertrichosis and generalized hypertrichosis. Localized hypertrichosis is limited to a particular area, while generalized hypertrichosis arises over the whole body. Hypertrichosis is also called Werewolf syndrome. It could be caused by spontaneous genetic mutation or pancreatic reversal mutation of the q22 band of chromosomes 8. Danny’s brother is normal, but he has hypertrichosis. I think Danny has a spontaneous genetic mutation. Hypertrichosis may be caused by the consumption of numerous medicines, such as phenytoin, streptomycin, psoralen, minoxidil, diazoxide, and cyclosporine. There is no permanent cure for hypertrichosis. Numerous methods are used to remove hairs, but temporary removal may last for various weeks or various hours. These methods include shaving, trimming, depilatories, waxing, threading, electrology, sugaring and plucking. Hirsutism and acquired hypertrichosis are related to each other. Hirsutism takes place in approximately 10% women.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
