A zoologist examined an intestine cell from a crayfish and counted 200 chromosomes, each consisting of 2 chromatids, at prophase I of mitosis. What would he expect to see in each of the four cells at telophase II of meiosis if he looked in the crayfish ovary?
View answer and explanation
Correct option: D
100 chromosomes, each consisting of 1 chromatid
Option D (100 chromosomes, each consisting of 1 chromatid) is correct because after meiosis II, the sister chromatids have separated, resulting in half the number of chromosomes as the original cell, each with a single chromatid.
