In the immune response the body reacts to each kind of
pathogen with a defense targeted specifically for that pathogen.
Answer:
- Populations must be very large -True
- The frequency of all genotypes must be equal. False
- Gene flow from other populations must be zero. True
- Matings must be random. True
- There should be no natural selection. True
Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- <u>Random matings</u>: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes.
- No superposed generations: each individual can leave their gametes in the pool only once.
- No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles.
- <u>No migration</u>: There is no incorporation of gametes originated in another population.
- <u>Infinite population size</u>: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q.
- <u>No natural selection</u>: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
