4x How many possible genetic combinations can arise from meiosis? A 2^wedge 21 B 2^wedge 22 C 2^wedge 23

The correct answer is C) $2^{23}$.<br /><br />During meiosis, the number of possible genetic combinations is determined by the number of chromosome pairs in an organism. In humans, there are 23 pairs of chromosomes, so the number of possible combinations is $2^{23}$, which equals 8,388,608.
