What is the meaning of the word allele?

What is the meaning of 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 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 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 best definition of the word 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 words describe alleles?

Scientific definitions for allele

Paired alleles (one on each of two paired chromosomes) that are the same are called homozygous, and those that are different are called heterozygous. In heterozygous pairings, one allele is usually dominant, and the other recessive.

Do all genes have 2 alleles?

Individual humans have two alleles, or versions, of every gene. Because humans have two gene variants for each gene, we are known as diploid organisms. The greater the number of potential alleles, the more diversity in a given heritable trait.

What is a sentence for allele?

Allele sentence example

To be affected by the disease, which shows autosomal recessive inheritance, a baby must inherit a mutant allele from each parent. In 5/6 patients the wild-type allele was lost in the tumor samples, suggesting a causal role for the mutations in RCC.

What is the relationship between gene and allele?

A gene is a portion of DNA that determines a certain trait. An allele is a specific form of a gene. Genes are responsible for the expression of traits. Alleles are responsible for the variations in which a given trait can be expressed.

WHAT IS A 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.

What is the meaning of allele Class 10?

Alleles are a pair of genes that occupy a specific location on a particular chromosome and control the same trait. Alleles may appear in pairs or in multiple forms of alleles, which affect a specific trait of the offspring. … If the pair of alleles are different, the organism’s genotype is called heterozygous.

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.
