Traits that are controlled a multiple gene loci. Polygenic traits.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.
Traits inherited by multiple alleles are those that are controlled by three or more different forms of a gene (alleles) at a single locus. Examples include human blood type, where the ABO gene has three common alleles (IA, IB, and i), and coat color in rabbits, which is determined by four alleles of the C gene (C, cch, ch, and c).
Recessive and dominant genes are the material that carries the traits of human beings. Traits of humans such as eye and hair color are determined by the combination of genes from your parents.
Gene
Traits that are controlled a multiple gene loci. Polygenic traits.
They are called Polygenic Traits.
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.

A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
or one gene, all by its lonesome.
Single gene traits are controlled by one gene and show simple Mendelian inheritance patterns, while polygenic traits are controlled by multiple genes and exhibit continuous variation due to interactions between these genes.
The opposite of polygenic traits is monogenic traits. Polygenic traits are determined by the interaction of multiple genes, while monogenic traits are controlled by a single gene.
