Question 1

Which substance is defective in Marfan syndrome?
◦ sphingolipids
◦ albumin
◦ fibrillin

Question 2

Why don't recessive alleles that cause severe disorders disappear from human populations?
◦ new alleles can arise by mutation.
◦ in heterozygotes, the dominant allele suppresses the recessive one but does not eliminate its presence.
◦ in heterozygotes, although the trait associated with the recessive allele is not demonstrated, the allele may be passed on to offspring.
◦ some recessive traits are not lethal nor do they interfere with reproduction.
◦ all of these.
