Question

Is a small population or a large population more likely to satisfy Hardy-Weinberg Equilibrium? Why?

Why is genetic isolation critical to speciation? What is the difference between pre and post-zygotic isolation? What is reinforcement and under what conditions would you expect to find evidence for reinforcement?

Answer 1

The large population is more likely to satisfy hardy-weinberg equilibrium because in the small population the sampling error will occur which will lead to arise the genetic drift. But in large population the sampling error will not found. That's why it is found in Hardy weinberg equilibrium.

the genetic isolation is critical to speciation. Because when genetic isolation is occur, then there is not found any mating between the individual of two isolated area. There will be not found any gene flow between individual of two population. That's why there is found only creation of different species in the population.

The Prezygotic isolation is defined as the reproductive isolation mechanism before the zygote formation such as mating incompartibility, different breeding behavior, geographical barrier. The post Zygotic isolation is founf after the zygote formation such as hybrid inviability.

reinforcement is the phenomena in which the natural selection will lead to to isolate to population. The evidences of reinforcement is found when the two population will be found in contact with each other.
