Question

Drag the labels to the table below to describe how allele frequencies would be affected under different conditions. remember that p is the frequency of the cr allele, and q is the frequency of the cw allele. labels may be used once, more than once, or not at all.

Answer 1

This the correct answers for this question:

Mutation - p will increase and q will decrease

In this case, "P" is representing homozygosity "Q" is representing genetic variation. Therefore the individuals are further decreasing genetic variation by increasing homozygosity in the genomes of their offspring. Mutation is a weak force for changing allele frequencies but is a strong force for introducing new alleles therefore it is the ultimate source of new alleles in plant pathogen populations.
Nonrandom mating - Frequency of plants with pink flowers will be much less than 2pq
Nonrandom mating occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals.

Natural selection - p and q will stay the same

The interactions between individuals and their environment are what determines whether their genetic information will be passed on or not. The sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.

Small population size - Changes in p and q cannot be predicted

Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error

Gene flow - p will decrease and q will increase

Migrants result change the distribution of genetic diversity within the populations, by modifying the allele frequencies.
