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.

What is the differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
How can one determine whether an individual is homozygous or heterozygous using gel electrophoresis?
In gel electrophoresis, an individual can be determined to be homozygous or heterozygous by looking at the number and size of bands on the gel. Homozygous individuals will show only one band, while heterozygous individuals will show two bands of different sizes.
Can you please distinguish homozygous and heterozygous individuals?
Homozygous individuals have two identical alleles for a particular gene (e.g., AA or aa), while heterozygous individuals have two different alleles for the same gene (e.g., Aa). Homozygous conditions often result in specific traits, while heterozygous conditions can lead to a blending or mix of traits from each allele.
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
What is the difference between homozygous and herterozygous?
Homozygous refers to having two identical alleles for a particular gene, while heterozygous means having two different alleles for the same gene. Homozygous individuals can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygous individuals have one dominant and one recessive allele.
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 differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.

1 What is the difference between homozygous and heterozygous?
Homozygous refers to having two identical alleles for a trait, while heterozygous refers to having two different alleles for a trait. In other words, homozygous individuals have either two dominant or two recessive alleles, while heterozygous individuals have one dominant and one recessive allele.
What crosses will only produce heterozygous offspring?
A cross between two individuals that are homozygous for different alleles will only produce heterozygous offspring. This is because each parent can only donate one type of allele, resulting in all offspring being heterozygous for that particular gene.
What is the probability of 2 heterozygous individuals producing a homozygous recessive offspring?
25%
Can you please distinguish homozygous and heterozygous individuals?
Homozygous individuals have two identical alleles for a particular gene (e.g., AA or aa), while heterozygous individuals have two different alleles for the same gene (e.g., Aa). Homozygous conditions often result in specific traits, while heterozygous conditions can lead to a blending or mix of traits from each allele.
Is asthma homozygous or heterozygous?
heterozygous

When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).

Homozygous individuals can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygous individuals have one dominant and one recessive allele.
What are the genotype a of a homozygous and a heterozygous tall pea plant?
homozygous- TT; heterozygous- Tt :)
Can you provide some Hardy-Weinberg equilibrium practice problems for me to work on?
Here are a few practice problems to help you understand Hardy-Weinberg equilibrium: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? In a population of 1000 individuals, 64 exhibit the dominant trait for a certain gene. What are the expected frequencies of the three genotypes (homozygous dominant, heterozygous, homozygous recessive) in the population? Try solving these problems using the Hardy-Weinberg equations and principles!
