Hardy Weinberg Principle

Gene flow is a concept best used to describe an exchange between …

• species.

• populations.

• chromosomes.

• males and females.

Which Hardy-Weinberg equation represents the genotype frequencies in a population?

• p + q = 1
• p2 + 2pq + q2 = 1
• p2 + pq2 + q2 = 1
• p + 2pq + q3 = 1

Which of the following is NOT a requirement for maintaining the Hardy-Weinberg equilibrium?

• An increasing mutation rate

• Random mating

• Large population size

• No migration

Which of the following would indicate a population is susceptible to evolution?

• The trait leads to non-random mating

• spontaneous mutation results in a trait that is an advantage over others

• natural selection pressure

• competition for survival is occuring

• a very large population with high genetic diversity

If a population experiences no migration, is very large, has no mutations, has random mating regarding a trait, and there is no selection, which of the following would you predict?

• The population will evolve, but much more slowly than normal.

• The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.

• The composition of the population's gene pool will change slowly in a predictable manner.

• Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.

Which of the following genotypes describes a frequency of homozygous?

• p²

• 2pq

• q²

• 1

Which of the following genotypes describes a frequency of heterozygosity?

• p²

• 2pq

• q²

• 1
