If a parent cell with 28 chromosomes undergoes meiosis, how many chromosomes will each resulting cell contain?

Meiosis is the process by which germ cells (gametes) are produced, resulting in a reduction of chromosome number by half. In the given situation, the parent cell has 28 chromosomes. During meiosis, this cell undergoes two rounds of division: meiosis I and meiosis II.

In meiosis I, homologous chromosomes are separated, resulting in two cells, each containing half the original number of chromosomes. Because the parent cell had 28 chromosomes, the division during meiosis I reduces this number to 14 chromosomes in each of the two resulting cells. Then, meiosis II further divides those cells, but it does not reduce the chromosome number again; it simply separates the sister chromatids.

Thus, each of the resulting cells after meiosis will contain 14 chromosomes, confirming that this is the correct choice.
