Frequent question: What is the best definition of the word allele?

Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.

WHAT IS A allele easy definition?

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 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 is the meaning of allelic?

Allelic: Pertaining to an allele, an alternative form of a gene. A single allele is inherited from each parent.

Which is the best example of an allele?

An example of an allele is the gene that determines hair color. Either of a pair of genes located at the same position on both members of a pair of chromosomes and conveying characters that are inherited in accordance with Mendelian law. Any of the possible forms in which a gene for a specific trait can occur.

How do you explain alleles to a child?

Allele – While the section of DNA is called a gene, a specific pattern in a gene is called an allele. For example, the gene would determine the hair color. The specific pattern of the hair color gene that causes the hair to be black would be the allele. Each child inherits two genes for each trait from their parents.

Where do alleles come from?

One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele.

How are alleles named?

Allele designations appear as superscripted short alphanumeric strings following the gene symbol of which they are an allele and serve as an acronym for the allele name. … Allele designations begin with a lower case letter if the allele is a recessive and begin with a capital letter otherwise.

How do you explain allele?

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.
