Unique Features of Meiosis

Each sperm cell surrounding this egg cell is trying to enter it and leave its packet of genetic information in the form of chromosomes containing DNA.  Only one will be successful.  In order for the newly formed organism to have the same number of chromosomes as its parents, the chromosome number must be halved when the egg and sperm are made.  This is accomplished by a process called meiosis.  Then, when one sperm successfully fertilizes the egg, the diploid chromosome number is restored.

Mitosis vs. Meiosis






Crossing-over occurs when portions of a chromatid on one homologous chromosome are broken and exchanged with the corresponding chromatid portions of the other homologous chromosome.  The DNA exchange that occurs during crossing-over adds even more recombination to the independent assortment of chromosomes that occurs in meiosis.  The number of genetic combinations that can occur among gametes is practically unlimited!  WOW!

Asexual reproduction creates clones. This hydra is in the process of reproducing asexually. The smaller hydra budding from the parent is genetically identical to the parent.
