Title: If natural selection is real, why do lethal recessive disorders still exist in populations?
Post by: JGIBBSON on Jul 17, 2021

If natural selection is real, why do lethal recessive disorders still exist in populations?
◦ Recessive disorders most frequently do not manifest until later in life, after the individual has reproduced.
◦ Recessive alleles remain hidden in carriers who are not affected by the disorder.
◦ There may be an advantage to individuals who are heterozygous.
