Answer
C. Four haploid genetically diverse cellsMeiosis is a type of cell division that produces gametes (sex cells) for sexual reproduction. It involves two rounds of division (meiosis I and meiosis II). Starting with a diploid cell (containing two sets of chromosomes), meiosis I separates homologous chromosomes, resulting in two haploid cells (each with one set of chromosomes). Meiosis II then separates sister chromatids (copies of each chromosome), resulting in a total of four haploid cells. Crossing over, which occurs during meiosis I, exchanges genetic material between homologous chromosomes, contributing to the genetic diversity of the resulting cells.
