Your Height
Trait is controlled by more than one pair of genes.
Polygenic Traits
A trait that is controlled by more than one gene is called polygenic. This means that multiple genes contribute to the expression of the trait, leading to a continuous range of phenotypic variation. Examples of polygenic traits include height, skin color, and intelligence.
Polygenic Traits
One gene controlled one trait within Mendel's study, but the sickle cell anemia effects more than one trait.
No, shoe size is not a Mendelian trait because it is influenced by multiple genes and environmental factors. It is considered a polygenic trait, meaning it is controlled by more than one gene, making it more complex than the simple Mendelian inheritance patterns.
A polyallelic trait is a trait controlled by multiple alleles (variants of a gene) at a single gene locus. This means there are more than two possible alleles that can influence the trait's expression, resulting in a range of phenotypic variations. This can lead to a complex inheritance pattern.
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
When more than one pair of alleles controls a trait, it is called polygenic inheritance. This means that multiple genes contribute to the expression of a trait, leading to a continuous range of variation rather than distinct categories. Examples of traits controlled by polygenic inheritance include height, skin color, and intelligence.
A sex-limited trait is a characteristic that is only expressed in one sex, either male or female. This trait is typically controlled by genes located on sex chromosomes. For example, male pattern baldness is a sex-limited trait that is more commonly seen in males than females. In this case, the trait manifests differently in males and females due to the influence of sex hormones and genetic factors specific to each sex.
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
Polygenic inheritance refers to the inheritance of a trait that is controlled by multiple genes, each with a small effect on the phenotype. Traits such as height, skin color, and intelligence are often influenced by multiple genes working together. This type of inheritance results in a continuous range of phenotypes rather than distinct categories.
