During the eugenics movement of the 1900s, it was believed that individuals affected with certain genetic disorders
should be sterilized to prevent transmitting the gene to future generations. Would such measures be effective? Why or
why not? What will be an ideal response?
Background:If
a genetic disorder is relatively rare (say 1 in 10,000 individuals), they generally assume that the
number of heterozygotes must also be rather low. In fact, if 1 in 10,000 members of a population are
homozygous for a recessively inherited disorder, it turns out that 1 in 50 (2%) members of the
population is a heterozygote, and there are about 200 times as many heterozygotes as there are
homozygous recessive individuals.
