4. During meiosis, one regular cell will eventually form four haploid cells each with a different set of DNA. Use the term crossing over to explain how one cell can form four genetically unique cells. __

Answer 1

During meiosis, crossing over occurs during prophase I when homologous chromosomes pair up and exchange segments of their DNA. This process creates new combinations of genetic material on each chromosome. As a result, when the cell divides into four haploid cells during meiosis II, each cell contains a unique set of DNA, contributing to genetic diversity.
