Step-by-Step Solution:
Step 1 of 3

Organismal Biology Dr. Carl S. Lieb Week 2 2/1/2016-2/3/2016 How to Calculate Allele Frequency Formula= # of copies of the allele in the population/total # of copies of all alleles in the pop. Ex (pg 308): Let’s say there are two alleles A & a. Possible allele combinations: AA, Aa, and aa N AA = number that are homozygous for the A allele NAa number that are heterozygous for both alleles Naa number that are homozygous for the a allele So then N AAN + Aa= toaal # of individuals in the population. Frequency of allele A: p= 2N +N 2N Frequency of allele a: q= 2N+N 2N Frequency of genotype AA: N / AA Frequency of genotype aa: N / N aa Frequency of genotype Aa: N /NAa p + q = 1 & 1-p=q & 1-q=p To predict the genotypic frequencies of the next generation: p +2pq+q or (p+q) 2 For any numbers given, plug them into the equations to get the frequencies. Full example is on page 308. Organismal Biology Dr. Carl S. Lieb Week 2 2/1/2016-2/3/2016 Random mating Every individual has equal opportunity of mating with another (panmixia) individual of the opposite sex. Assortive mating Individuals with similar traits mate; alters allele frequencies Positive: Individuals select mates that resemble themselves Negative: Individuals select mates that are different
