mutation-selection balance

... equal to μ, the mutation rate (p = μ). We can use the same principles to predict the relationship between mutation and selection against recessive alleles. The Hardy-Weinberg principle showed that most copies of harmful recessive alleles are found in heterozygotes and are thus protected from the ...

Meiosis I is when the alleles separate, so you should only place one A or a and one B or b on each side of the dividing cell. The two forms of a gene are present on the two ...
