Expression of a shortened skin keratin gene in place of the normal keratin gene in transgenic mice results in a phenotype in which mice have
A) thick skin.
B) no hair.
C) fragile, easily blistered skin.
D) white hair.

Question

Quizplus · Accepted Answer

Shortened skin keratin gene is likely to result in a weaker and easily blistered skin due to improper formation of intermediate filaments, which provide strength to the skin. Thick skin and white hair are not expected outcomes of this genetic alteration. The hair phenotype is not specified in the prompt, so it cannot be assumed that the mice will have no hair.
