Inbreeding allele frequency

WebA. Offspring produced by inbreeding have high biological fitness. B. Inbreeding increases the rate of purifying selection. C. Inbreeding changes allele frequencies in a population. D. Inbreeding increases random mating. Which of the following is associated with inbreeding? A. The frequency of homozygotes decreases in a population. Webfreq (A1)= 0.9, so freq (A2)= 0.1. Freq (A1A2)= q^2 = (0.1)^2= 0.01. The number of babies with cystic fibrosis= 2500 (0.01)= 25. 8. Suggest why inbreeding could cause recessive deleterious alleles for cystic fibrosis to be "purged" from a population. Inbreeding causes an increase in the number of homozygotes.

WebFeb 19, 2024 · The allele frequency (or gene frequency) is the rate at which a specific allele exists within a population. Allele frequencies can be expressed as a decimal or as a percent and always add up to 1, or 100 percent, of the total population. The gene pool is the sum of all the alleles of all genes in a population.
