A typical human would have around 1-2 lethal genes if homozygous for lethal alleles. Lethal genes are usually rare in the human population due to the negative impact on survival and reproduction.

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).


When both alleles of genes are the same what is the individual?

homozygous


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).


Two identical alleles for a particular gene is what?

Having two identical alleles for a particular gene is known as homozygous. This means that both copies of the gene are the same, either both dominant or both recessive. Homozygosity can result in a specific trait being expressed, depending on the nature of the alleles.


What is the difference between heterzygous and homozygones?

Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles for the same gene. Homozygotes can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygotes have one dominant and one recessive allele.


Is the trait TT heterozygous or homozygous?

Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.


What is an organism with two genes for a trait called?

An organism with two like alleles for a trait is homozygous for that trait.


What is homozygous-?

Every gene has a dominant and recessive allele, homozygous is just when a gene has either two dominant alleles or two recessive alleles.


A person having two genes that are alike is said to be?

Homozygous. This means that both alleles for a particular gene are the same, either both dominant or both recessive.


What is Having two unlike genes for the same trait?

When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.


What has 2 genes or alleles like TT or tt?

An organism with two genes or alleles, such as TT or tt, is said to be homozygous for a particular trait. In this case, TT represents a homozygous dominant genotype, while tt represents a homozygous recessive genotype. These genotypes can influence the organism's phenotype, or observable characteristics, depending on the dominance of the alleles involved. For example, if T is dominant over t, the phenotype of TT and Tt would be the same, while tt would have a different phenotype.


What is the difference between homzyguos and heterozyous?

Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
