The number of possible chromosomal orientations during metaphase I is equal to the number of chromosome pairs raised to the 2nd power. A. True
B. False

A

Explanation:

The statement is entirely true.

During metaphase 1 of meiosis, each tetrad - a chromosome consisting of 4 chromatids - formed in prophase has 2 possible orientations. Hence, the total number of possible chromosomal orientations would be 2 raised to the power of the number of chromosome pairs present in the cell.

For example, humans have 23 pairs of chromosomes in each of their cells, hence, the total number of possible chromosomal orientations would be which is equal to 8,388,608 possible orientations.

The correct option is A.
