What is a simple definition of an allele?

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

What best defines an allele?

An Allele is best defined as. a specific form of gene. An allele is an alternative form of a gene located on a specific site of a chromosome.

What is alleles short answer?

Alleles are also genetic sequences, and they too code for the transmission of traits. … The short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent.

What does allele mean example?

The definition of alleles are pairs or series of genes on a chromosome that determine the hereditary characteristics. An example of an allele is the gene that determines hair color.

What is the definition of an allele quizlet?

An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring. … They are exactly like their parents. It only has one division and that leads to two cells.

What is an allele and what is its function?

Alleles are different forms of the same gene which are located on the same part of the chromosome. Genes are made up of information needed to produce different proteins, so alleles carry information to produce different versions of the same protein.

How do you identify alleles?

To identify whether an organism exhibiting a dominant trait is homozygous or heterozygous for a specific allele, a scientist can perform a test cross. The organism in question is crossed with an organism that is homozygous for the recessive trait, and the offspring of the test cross are examined.

What is allele class 10th?

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.

What is an allele Class 12?

An allele is an alternative form of a gene. It is located at a specific position on a specific chromosome. These can be passed on from parents to offspring through sexual reproduction.

What is Allelism?

Allelism refers to any of the several forms of a gene. These genetic variations arise usually through mutation and therefore are responsible for hereditary variations. … When there is a gene existing in more than two allelic forms this condition is referred to as multiple allelism.
