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:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Step-by-step 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.
