How do most autosomal recessive
alleles, that lead to lethal diseases,
persist in human populations?
The disease-causing allele can
"hide" in the heterozygous
condition.
These diseases only affect
individuals who are XY.
These diseases usually take effect
later in life after people have had
children.
The environment plays a large role
in determining whether the gene is
expressed.
