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 A allele 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 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 the main function of alleles?
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.

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 allele concept?
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. … Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.
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.
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.
