To produce transgenic bacteria that make insulin, which of the steps listed below would a scientist do last?
a. insert the human insulin gene into a plasmid.
b. extract the insulin from the bacterial culture.
c. cut out the insulin gene from human dna.
d. transform bacteria with the recombinant plasmid.

The correct answer is - =X+Y males and XwXwY females

Explanation:

during meiosis, XXY females are prone particularly to X chromosome during meiosis. This nondisjunction can lead to the production of both X+Y red-eye male and XwXwY white eye females.

The red-eye male has resulted from the fertilization of X bearing sperm and Y bearing egg. The XwXwY is formed from Y bearing sperm and an egg with two chromosome fertilization.
