Meiosis - GED Science

Meiosis allows for increased genetic variation through crossing over and independent assortment. These processes result in daughter cells that are non-identical to the original parent cell. Crossing over describes the exchange of portions of DNA between homologous chromosomes, generating unique allelic combinations. Independent assortment means that the daughter cells of meiosis will have a mixture of genetic material from each set of the organism's alleles, representing DNA from both the mother and father sets of genes. The product of meiosis is four daughter cells that are genetically unique.

Each daughter cell of meiosis has only one copy of each gene, meaning that they are haploid. Only gametes (sex cells) undergo meiosis, allowing for sexual reproduction. The fusion of two haploid gametes results in a diploid cell.

Meiosis is the process that creates gametes (eggs and sperm). The cell divides twice, creating 4 unique daughter cells that contain half (haploid) of the genetic information of the parent cell. Somatic cells are body cells and they are produced via mitosis.

Crossing over is an event that recombines DNA between homologous, non-identical chromosomes. The result is an increase in genetic variation because the resulting daughter cells have slightly different genetic combinations than the original parent cell. Crossing over only occurs during meiosis. This is because homologous chromosomes are only in adjacent positions during prophase I. Crossing over cannot occur during mitosis because this alignment is never present; daughter cells of mitosis are always genetically identical to the parent cell.

Sister chromatids separate during anaphase of mitosis and anaphase II of meiosis. Chromosomes condense and the nuclear membrane dissolves during prophase of mitosis and prophase I of meiosis.
