Gene frequencies of populations Not in Hardy-Weinberg equilibrium
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
How can someone share 50% of their DNA with their parents yet all humans share 99.9%?
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
Why is the strength of genetic drift inversely proportional to the population size?
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
Hardy Weinberg principle?
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
Books on population or evolutionary genetics?
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
Is it mostly true that predators or parasites traverse wider spatial areas than their prey or hosts?
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
