Question:

Albinism in blue jays is a recessive trait. Over time, the percentage of albino blue jays in a population will remain stable in a population from generation to generation if which conditions are met?

Answer:

  1. Random matings
  2. No superposed generations
  3. No mutations
  4. No migration
  5. Infinite population size
  6. No natural selection

Explanation:

If frequencies stabilize in the population, generation after generation, then it means the population met Hardy-Weinberg equilibrium. Populations in H-W equilibrium will get the same allelic frequencies generation after generation.

Hardy-Weinberg assumption for a population in equilibrium:  

• Random matings: Any individual get crossed with any other individual

• No superposed generations: each individual can leave their gametes in the pool only once.  

• No mutations: No mutations originate in any new gametes.

• No migration: No incorporation of gametes from other populations    

• Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.  

• No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
