What is difference between gene and allele?
What is difference between gene and allele?
Gene is defined as a section of DNA that encodes for a certain trait. An allele is defined as a variant form of a gene. It determines an organism’s genotype. It determines an organism’s phenotype.
Does gene mean 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 an allele trait and gene?
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 a set of alleles for a gene?
The fact that genes exist in alternate forms, called alleles, forms the basis for the study of population genetics.
What are facts about allele?
Dominance. In a heterozygote the effect of one allele may completely ‘mask’ the other.
How do alleles determine traits in genetics?
Alleles determine different traits, which carry different phenotypes. As an example, the gene responsible for the flower color of pea plant ( Pisum sativum ) carries two forms, one allele determines the white color, and the other allele determines the red color. These two phenotypes red and white are not expressed simultaneously in one individual.
What is an allele in biology?
allele – (genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character; “some alleles are dominant over others”. allelomorph.
What does allele mean?
Freebase(0.00 / 0 votes)Rate this definition: Allele. An allele, or allel, is one of a number of alternative forms of the same gene or same genetic locus. It is the alternative form of a gene for a character producing different effects. Sometimes, different alleles can result in different observable phenotypic traits, such as different pigmentation.
