Chapter 26, Problem 2QSDC

Discuss the role of mutation in the origin of genetic polymorphisms. Suppose that a genetic polymorphism involves two alleles at frequencies of 0.45 and 0.55. Describe three different scenarios to explain these observed allele frequencies. You can propose that the mutations that produced the polymorphism are neutral, beneficial, or deleterious.

Biology laboratory problem Please help. thank you You have 20 ul of DNA solution and 6X DNA loading buffer solution. You have to mix your DNA solution and DNA loading buffer before load DNA in an agarose gel. The concentration of the DNA loading buffer must be 1X in the DNA and DNA-loading buffer mixture after you mix them. For that, I will add _____ ul of 6X loading buffer to the 20 ul DNA solution.
