NEET BIOLOGY

Detailed explanation-1: -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-2: -The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

Detailed explanation-3: -If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.

Detailed explanation-4: -An individual that contains two different alleles of a gene is heterozygous.

Detailed explanation-5: -Codominance Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.
