GENETIC BASIS OF INHERITANCE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One gene from an inherited pair is called this.
A
an allele
B
a cell
C
a chromosome
D
a trait
Explanation: 

Detailed explanation-1: -An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.

Detailed explanation-2: -An allele is one of two or more alternative forms of a gene, and they are found at the same place, or locus, on the chromosome. Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene.

Detailed explanation-3: -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.

Detailed explanation-4: -Listen to pronunciation. (jeh-NEH-tik PREE-dih-spuh-ZIH-shun) An inherited increase in the risk of developing a disease. Also called genetic susceptibility, hereditary predisposition, and inherited predisposition.

Detailed explanation-5: -Each variation of a gene is called an allele (pronounced ‘AL-eel’). These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.
