Nonrandom mating tends to the frequencies of genotypes.

a. increase; homozygous

b. decrease; homozygous

c. increase; heterozygous

d. decrease; homozygous recessive

e. increase; homozygous dominant

Answer;

A. increase ; homozygous

Explanation;

-Nonrandom mating occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. When the probability is the same, then individuals are just as likely to mate with distant relatives as with close relatives -- this is random mating.

-Nonrandom mating tends to increase the frequencies of homozygous genotypes. Nonrandom mating can take two forms namely; inbreeding and outbreeding.

-Inbreeding changes genotype frequencies, not allele frequencies: Homozygotes increase in frequency, heterozygotes decrease in frequency.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
