What is heterozygous? Your inherited characteristics are determined by your genes. Zygosity refers to the similarity of genes for a trait in an organism. If both genes are different, the organism is heterozygous (hetero = different) for that trait. If both genes are the same, the organism is homozyous (homo = same).
Heterozygous.
A heterozygous has 2 different alleles for a trait.
A trait that is not expressed when another is present is referred to as a recessive trait.
An organism with two like alleles for a trait is homozygous for that trait.
genes and the environment
An organism that has genes that are alike for a particular trait is called homozygous for that trait. This means that it has two identical alleles for that specific gene.
Incomplete dominance is a trait that can result when an organism receives genes for two different forms of the same trait. In this case, neither form of the trait is fully expressed, leading to a blending of the two forms.
Non-allelic genes are genes located on different chromosomes that do not directly influence each other. They can affect the expression of a specific trait in an organism through independent pathways, leading to a combination of different genetic factors influencing the trait.
An organism with two like genes for a trait is called homozygous for that trait.
trait
A genotype is an organism's combination of genes that forms a trait.
