Question

allele frequency in biology short 1 sentence definition, 2 simple examples, and 1 short sentence using it 9th grade level

Answer 1

Definition: Allele frequency is the percent (or proportion) of all copies of a gene in a population that are a particular allele.

Examples:
1) 10 plants have 2 copies of the gene each = 20 total alleles; if 14 copies are the R allele, allele frequency of R = 14/20 = 70%.
2) 50 people have 100 total alleles; if 40 copies are the b allele, allele frequency of b = 40/100 = 40%.

Short sentence using it: The allele frequency of the R allele in the plant population is 70%.
