What are the five tenets of the Hardy-Weinberg principle? My teacher and textbook gave different lists...?

Both my teacher and textbook said the first three were no evolution, no mutations, and no gene flow.

However, the textbook said there was also an infinitely large population and all individuals survive and produce the same number of offspring.

My teacher said the fourth and fifth ones were no genetic changes and no selective forces respectively. Are these related at all to the two mentioned above? Thanks and God bless.What are the five tenets of the Hardy-Weinberg principle? My teacher and textbook gave different lists...?
It may be a matter of semantics or interpretation. Here are the 5 that I use:

1. No migration (in or out)

2. No nonrandom mating

3. No mutations

4. No genetic drift

5. No natural selection



The "large population" requirement (as I explain it) is to make H-W calculations more accurate. Of course, the no natural selection requirement is not possible in a natural population; natural selection is always at work. This is why the H-W Principle never applies in nature...What are the five tenets of the Hardy-Weinberg principle? My teacher and textbook gave different lists...?
five tenets are:

1. there should be no mass immigration or emigration.

2. all the individuals in a population should be capable of mating.

3. there should be no new mutations in genes.

4. individuals should randomly mate in a population.

5. the population must be large and no genetic selection should be there.
