meisosis and genetic variation

• What is meiosis?

  cell division that produces 4 genetically different daughter haploid cells from a diploid parent cell
• Process of meiosis

  1. Genetic information duplicates and the chromosomes form pairs

  2) First division - homologous pairs pair up and undergo crossing over and then are separated and each pair goes into one of the 2 daughter cells3) Second division - the chromatids move apart and 4 genetically different daughter cells are formed
• How does meiosis create genetic variation?

  1. independent segregation of homologous chromosomes

  2. new combinations of maternal and paternal alleles by crossing over
