Many genetic studies, particularly those of recessive traits, have focused on small isolated human populations, such as those on islands. Which are major advantages that isolated populations might provide for the study of recessive traits? Some recessive traits that are rare in most large populations may be relatively common in some small populations. Geneticists are more likely to be able to control mating choices in small populations. Autosomal dominant traits will be more likely to be found in such populations. Small populations likely will experience a high mutation rate and thus produce more genetic variation for study. Inbreeding, which is more common in small populations, will tend to increase the frequency of recessive phenotypes.

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patients have muscles that weaken over time because they have absent or decreased dystrophin, a muscle protein. they rarely live past their twenties. how likely is it for a woman to have this condition? a) women can never have this condition.b) one-fourth of the daughters of an affected man would have this condition.c) one-half of the daughters of an affected father and a carrier mother could have this condition.d) only if a woman is xxx could she have this condition.
