How would selection against heterozygous individuals over many generations affect the frequencies of homozygous individuals?

If heterozygous individuals are not favored, then the frequency of heterozygous individuals will decrease as the frequency of homozygous individuals increase.
This can be shown using the Hardy-Weinberg equation for allele frequencies in a population:
p2 + 2pq + q2 = 1 where q2 & p2 are the frequencies of the two different homozygous individuals (eg. aa and AA) and 2pq is heterzygous (eg. Aa). As the equation shows, if 2pq decreases, the other two variables must increase to compensate.

An organism that has two identical alleles for a trait?
Are known as homozygous. Homozygous individuals can also be called 'purebred'. Organisms with two different alleles are known as heterozygous.
Can you please distinguish homozygous and heterozygous individuals?
When an organism contains two identical copies of the gene at a specific locus, it is known as homozygous. On the other hand, if it contains two different alleles, it is called heterozygous.
Is the BB genotype heterozygous or homozygous?
Heterozygous
Is type 2 diabetes homozygous or heterozygous?
homozygous
What is the probability of offspring for 2 heterozygous dogs?
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
What is the probability of 2 heterozygous individuals producing a heterozygous recessive offspring?
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
What is the probability of 2 heterozygous individuals producing a homozygous recessive offspring?
25%
What crosses will only produce heterozygous offspring?
There only certain crosses that will produce heterozygous offspring. These are heterozygous vs heterozygous, homozygous vs homozygous and heterozygous vs homozygous.

Is asthma homozygous or heterozygous?
heterozygous
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
What are the genotype a of a homozygous and a heterozygous tall pea plant?
homozygous- TT; heterozygous- Tt :)

Homozygous dominant (Ex:AA) Heterozygous (Ex:Aa) Homozygous recessive (Ex:aa)
