population genetics

Hardy-Weinberg equilibrium assumes p^2+2pq+q^2 of a single gene, generation after generation ie. gene frequencies DO NOT change over time. If this was true in nature populations would never... more

I have heard that humans share 99.9% of their DNA with other humans. I have also heard that a child shares 50% of their DNA with their parents. How do I resolve this apparent contradiction? It has... more

I saw a concept on the Internet that says "the strength of genetic drift is inversely proportional to the population size". I don't know why they are **inversely proportional**? Can somebody... more

The principle is that sum total of all allelic frequencies is 1.Individual frequencies for example can be named p,q.In a diploid cell , p and q represent the frequency of allele A and a... more

I have recently been involved in collaborations that require me to model the population genetics of eukaryotic populations. I fear I may either be "re-inventing the wheel" or making conceptual... more

Does it tend to be true that as you go up the food chain, the species tend to cover wider areas? I am basically asking whether a population's prey varies spatially more than a population's... more

Here is a question from the book *SAT II Success Biology E/M* (where the SAT is the exam taken by the American high school students): > Which of the following statements is true about... more
