Yes - recessive alleles can be eliminated from the gene pool.
However, heterozygous individuals (those with one recessive allele) are harder to identify if the allele is recessive, so if talking about artificial (selective) breeding, the process may take some time.
Yes, it is possible for an individual to have recessive homozygous alleles if both copies of a particular gene are the same and carry the recessive trait. This would mean that the individual inherited the same recessive allele from both parents.
Yes.
Mendelev worked with pea plants. He had pure bred red flowers that means they were homozygous for the red allele; pure bred white flowers were homozygous for the white flowering allele. When he crossed them he found that all of the offspring were red but when he interbred these second generation flowers he got 75% red and 25% white flowers. These third generation white flowers were homozygous for the recessive white allele.

When an individual have two identical alleles for the same trait it is called?
Having two similar alleles for a trait is called being homozygous. It is possible to be homozygous for a dominant or recessive trait.
When the alleles present for a trait are the same. the genes are called?
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
What are the two terms for having matching alleles for a certain trait?
The two terms for having matching alleles for a certain trait are "homozygous dominant" (two dominant alleles) and "homozygous recessive" (two recessive alleles).
What are the three different combinations of alleles?
If the gene for a trait has two alleles, one dominant (D) and one recessive (d) there are three possible combinations in the genotype: DD (homozygous dominant) Dd (heterozygous) dd (homozygous recessive)
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
When an individual have two identical alleles for the same trait it is called?
Having two similar alleles for a trait is called being homozygous. It is possible to be homozygous for a dominant or recessive trait.
A trait produced from two alleles that are alike is?
A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
Having a gene pair with two dominant alleles means that both alleles are expressing themselves over the recessive alleles, leading to a dominant trait. Conversely, having two recessive alleles means that the trait will be recessive. This situation is known as homozygous dominant and homozygous recessive, respectively.
What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
When the alleles present for a trait are the same. the genes are called?
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
What are the two terms for having matching alleles for a certain trait?
The two terms for having matching alleles for a certain trait are "homozygous dominant" (two dominant alleles) and "homozygous recessive" (two recessive alleles).
A homozygous genotype where both alleles are recessive are called?
A homozygous genotype with both alleles being recessive is called a homozygous recessive genotype. This means that both copies of the gene are the same recessive allele, resulting in the expression of the recessive trait.
What are the three different combinations of alleles?
If the gene for a trait has two alleles, one dominant (D) and one recessive (d) there are three possible combinations in the genotype: DD (homozygous dominant) Dd (heterozygous) dd (homozygous recessive)

What are the different forms of a gene either dominant or recessive?
Genes can exist in different forms called alleles. Dominant alleles are expressed when present, masking the effects of recessive alleles. Recessive alleles are only expressed when two copies are present, one from each parent. This results in a wide range of possible genetic combinations and expressions.
What genotype is homozygous?
A homozygous genotype refers to having two identical alleles for a particular gene. It can be either homozygous dominant (two dominant alleles, such as AA) or homozygous recessive (two recessive alleles, such as aa).
What is a Genotype in which both alleles are the same?
A genotype in which both alleles are the same is called homozygous. This means that the individual has two identical alleles for a particular gene (e.g., AA or aa). Homozygous genotypes can be either homozygous dominant (both alleles are dominant) or homozygous recessive (both alleles are recessive).
