What is the relationship between chromosome gene locus and allele?
A specific position along a chromosome is called a locus. Each gene occupies a specific locus (so the terms locus and gene are often used interchangeably). Each locus will have an allelic form (allele). The complete set of alleles (at all loci of interest) in an individual is its genotype.
So we can say that a cell contains chromosomes and that chromosome contains DNA. 3)Gene is a structure that is made up of DNA and is arranged on the chromosome and the alleles are various forms of a gene that are almost similar to each other with little difference in the sequence of DNA.
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 the difference between gene locus and allele?
Alleles are variants of the same gene that occur on the same place on a chromosome. … A locus refers to the location on the chromosome where the gene is found. Loci is the plural form of locus.
What is the relationship between genes and alleles quizlet?
A gene is a specific section of a chromosome where the base pairs that code for the characteristic are stored whereas an allele is the actual sequence of the base pairs in the section.
What do the terms gene and allele have in common quizlet?
What do the terms gene and allele have in common? Both could refer to the same DNA sequence.
Different forms of a gene are called alleles. … The alleles an individual has at a locus is called a genotype. The genotype of an organism is often expressed using letters. The visible expression of the genotype is called an organism’s phenotype.
