what is the end result of mitosis
universal donor
a mistake in meiosis

who is the father of genetics
dominant allele
what happens during meiosis that leads to addition or deletion of chromosomes
selection towards PQ
a karyotype is performed on a cell that is in which portion of the cell cycle
sickle cell anemia is an example of what selection

were outcompeted by modern humans 40,000 years ago
