Final answer:
The frequency of the F374 allele in Germans, which is 0.965, equates to 96.5%. Allele frequency is a measure of how common an allele is within a population's gene pool and is crucial for understanding evolutionary changes.
Step-by-step explanation:
The frequency of the F374 allele in Germans is 0.965, which is equivalent to 96.5%. The concept of allele frequency in population genetics is crucial for understanding how often an allele occurs in a gene pool relative to the other alleles for that gene. When looking at allele frequencies, a change over time in these percentages can signify evolution within the population.
In examples provided, allele frequencies can also be used in the Hardy-Weinberg principle to predict genotype frequencies in a population. This principle relies on the equation p² + 2pq + q² = 1, where p and q represent the frequencies of two alleles, with p + q equal to 1. For instance, if the frequency of allele A (p) is 0.4, the frequency of the AA genotype (p²) would be 0.16 or 16%.
