What effect do mutations have on a population's genetic variation
Homework Answers
Mutation is the sudden change in the DNA. Mutations change the sequence of the DNA. When the sequence of the DNA is changed then mRNA made will also be faulty. This mRNA will further make a faulty protein. This faulty protein will perform some or the other function in the human body. This faulty protein might provide an advantage to the individual or might cause a problem.
So, in this way mutation causes variations in the genome of the organisms.

Mutations are the ultimate source of genetic variation. However, they usually occur at very low frequency. Assume a mutation resulting in a novel allele occurs in a gene of one individual in a population of 500 diploid individuals. The allele does not affect the fitness of the individual carrying the mutation. How long will it take for the allele to reach a frequency of 0.5 in the population? A. It cannot reach a frequency of 0.5. It will eventually reach...

Discuss how population and/or family pedigree genetic studies use genetic markers to distinguish between DNA variation [Hint: you may wish to include a discussion on Hardy-Weinberg Equilibrium (HWE), finding causative mutations responsible for a Mendelian disease and/or using SNPs in GWAS for complex traits/disorders].

I don't understand what this questions means?!?! What does it mean there is genetic variation for a specific behavior? I thought it was talking about how a specific gene can affect specific behaviors? Is that not the same with diseases? How a specific deletion or misense can determine Sickle Cell? How is it not the same with behaviors? That doesn't make sense. What does it mean "genetic variation for a specific behavior"? Also what does it mean "present in strains...
