What are the same alleles?

When two factors or alleles are the same?

If the two alleles are identical, the individual is called homozygous for the trait; if the two alleles are different, the individual is called heterozygous.

What is allele and its example?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Is eye color an allele?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.

What term describes a pair of alleles that are the same?

Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. … An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.

What is different between two alleles of the same gene?

If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

What is the best definition of allele?

An allele is one of a pair of genes that appear at a particular location on a particular chromosome and control the same characteristic, such as blood type or color blindness. Alleles are also called alleleomorphs. Your blood type is determined by the alleles you inherited from your parents.

What is a gene VS allele?

A gene is a unit of hereditary information. Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits.

What is an allele Class 10?

Alleles are a pair of alternative forms of a gene. Each gene is present in two alternative forms, each called an allele. Each allele controls a single trait. Traits can be either dominant or recessive.
