Meiosis is cell division that creates gametes in sexually reproducing organisms. Chromosomes are randomly assorted and are distributed independently into four gametes. Which of the following BEST describes the genetic material in the four gametes

Question

Each gamete created during meiosis has a unique genetic makeup
The genetic material in each gamete is exactly the same
Gametes contain double the amount of chromosomes as the parent cell
The chromosome number of the gametes is equal to that of the parent cell

Answer 1

The statement that BEST describes the genetic material in the four gametes created during meiosis is:

Each gamete created during meiosis has a unique genetic makeup.

This is due to the processes of crossing over and independent assortment during meiosis, which lead to genetic variations in the gametes. The other statements are incorrect because:

• The genetic material in each gamete is not exactly the same.
• Gametes contain half the number of chromosomes compared to the parent cell (not double).
• The chromosome number of the gametes is half that of the parent cell, not equal.
