Explain the major difference between daughter cells formed by mitosis and those formed by meiosis. What occurs when two daughter cells formed during meiosis fuse?
What will be an ideal response?
In mitosis, each daughter cell receives two copies of each chromosome. Cells with two copies of each chromosome are diploid (2n) and have 46 chromosomes. In meiosis, members of a chromosome pair separate from each other, and each daughter cell receives a haploid (n) set of 23 chromosomes. These haploid cells form gametes (sperm and egg). Fusion of two haploid gametes in fertilization restores the chromosome number to the diploid number of 46, providing a full set of genetic information to the fertilized egg.
