During meiosis in humans, 1 diploid cell (with 46 chromosomes or 23 pairs) undergoes 2 cycles of cell division but only 1 round of DNA replication. The cells will continue to divide until a gamete is formed. Widow's Peak, Mid-Digital Hair, ABO Blood Groups, PTC Tasting, Autosomal Dominant; A and B genes are dominant over the O gene, Sickle Cell Anemia; Heterozygous offspring exhibits some signs (some cells are sickled while others are not) and function normally unless in low oxygen conditions and are resistant to malaria, When both alleles are present in an individual and both are expressed; Due to multiple alleles where some genes have more than two alleles, such as Blood Types; Type AB blood has both I^A and I^B present; Type O blood has ii, Most common blood type (45% of population), Least common blood type (4% of population), Located on the X Chromosome; Males only need one recessive gene to express the trait; ex. What is the law of independant assortment? Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell. "Odds against a direct hit are very low but when your life is in danger, you don't worry too much about the odds.
