question 84

Multiple Choice

Studies of enzyme genotypes and flight in Colias butterflies showed that

• A) males that are heterozygous for the PGI gene are always inferior in flight compared with homozygotes.
• B) males that are heterozygous for the PGI gene have greater mating success than homozygous males because they are able to fly farther in a broad range of temperatures.
• C) genotypes for the PGI gene do not affect flight ability.
• D) flight ability and mating success are not correlated.
• E) flight ability can be explained by Muller's ratchet.
