    In genetics, the term heterozygous refers to having two different alleles at a specific gene locus on a pair of homologous chromosomes. Each parent contributes one allele to their offspring, resulting in a combination of different alleles for a particular gene. For example, if an individual inherits one allele for brown eyes (B) from one parent and one allele for blue eyes (b) from the other parent, they are heterozygous (Bb) for that gene. Heter...

    • Having different alleles for a particular trait.
    • When two different versions of a gene are present.
    • The interaction between the two alleles affects which traits are expressed.
    • It is the opposite of homozygous, where there are two identical alleles for a trait.

    Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.

    When you’re heterozygous for a specific gene, it means you have two different versions of that gene. The dominant form can completely mask the recessive one, or they can blend together. In some cases, both versions appear at the same time. The two different genes can interact in various ways.

    Heterozygous is a term used in genetics to describe when two variations of a gene, known as alleles, are paired at the same location (locus) on a chromosome. By contrast, homozygous is when there are two copies of the same allele at the same locus.

    The term heterozygous is used to describe a cell, a nucleus, or an individual organism that carries different or non-identical alleles for a particular trait at the same loci on homologous chromosomes. It means that the alleles that code for the same gene or trait are dissimilar, as opposed to homozygous wherein the alleles are identical.
