Question: What is having the same alleles for a trait?

When you have the same alleles for a trait?

Both alleles for a trait are the same in an individual. They can be homozygous dominant (YY), or homozygous recessive (yy). heterozygous; usually referring to the offspring of two true-breeding (homozygous) individuals differing in the traits of interest.

What is having the same alleles?

An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous.

What refers to having identical alleles for a single trait?

Purebred. –homozygous. term used to refer to an organism that has two identical alleles for a particular trait.

Is homologous the same as homozygous?

However, in genetics, two chromosomes located on the same position on a karyotype are said to be homologous chromosomes. … The term homozygous in genetics refers to the situation where two genes or alleles for a particular trait are the same on a pair of homologous chromosomes.

What is homologous allele?

Homologous Means “The Same”

Corresponding loci on each paired chromosome are called homologues. Homologous alleles are the alleles that inhabit these homologous loci. They code for the same trait even if they contain different information. For example, one chromosome may have an allele that codes for blue eye color.

What does homozygosity mean?

Homozygous describes the genetic condition or the genetic state where an individual has inherited the same DNA sequence for a particular gene from both their biological mother and their biological father. It’s often used in the context of disease.

What is it called when a trait has two identical alleles?

If an organism contains two identical alleles for a particular trait, the genotype for this trait is said to be homozygous.

When both alleles for a single trait are the same the alleles are described as?

If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.

When there are two identical alleles for a trait?

Homozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa). Individuals who are homozygous for a trait are referred to as homozygotes.
