Differencebetween polygenic and pleiotropic traits
Wiki User
∙ 10y ago
Pleiotropy occurs when a single gene influences multiple traits or characteristics, while polygenic inheritance involves the combined effect of multiple genes on a single trait or characteristic. Pleiotropy involves one gene affecting many aspects of an organism's phenotype, whereas polygenic inheritance involves many genes contributing to one aspect of an organism's phenotype.

Define and distinguish between pleiotropy and polygenic inheritance?
Pleiotropy occurs when a single gene influences multiple, seemingly unrelated traits or phenotypes. Polygenic inheritance, on the other hand, involves the combined effect of multiple genes on a single trait. In pleiotropy, one gene has multiple effects, whereas in polygenic inheritance, multiple genes each have a small additive effect on a trait.
What is the difference between pleiotropy and polygenic inheritance?
Pleiotropy refers to a single gene influencing multiple phenotypic traits, while polygenic inheritance involves multiple genes contributing to a single trait. Pleiotropy can lead to diverse phenotypic effects, while polygenic traits are often influenced by the additive effects of multiple genes.
What would be your clue that a character would have polygenic inheritance pattern?
If the trait in question shows a wide range of variation and does not follow a simple dominant-recessive pattern, it could indicate polygenic inheritance. Additionally, if the trait cannot be easily categorized into discrete categories or if it is influenced by multiple genes located on different chromosomes, it may be a sign of polygenic inheritance.
When a single trait is affected by more than one gene locus this called?
This is called polygenic inheritance. Multiple genes contribute to the expression of a single trait in polygenic inheritance, resulting in a continuum of phenotypic variation. Traits like height, skin color, and intelligence are influenced by multiple gene loci.
What type two or more genes control a trait?
Polygenic inheritance is when two or more genes interact to control a trait. Each gene contributes to the phenotype in an additive manner, resulting in a continuous range of variations for the trait. Examples include human height and skin color.
More phenotypes than expected may result from polygenic inheritance because of what?
pleiotropy

What is the opposite of pleiotropy?
The opposite of pleiotropy is "monogenic" or "simple genetic inheritance," where a single gene controls only one specific trait or function in an organism. In contrast, pleiotropy refers to a situation where a single gene influences multiple, seemingly unrelated phenotypic traits.
How genes affect characteristics?
It is a polygenic character

What is inheritance determined by the interaction of two or more pairs of genes?
Polygenic inheritance.
What can polygenic inheritance can explain?
Polygenic inheritance can explain traits that are influenced by multiple genes, such as height, skin color, and intelligence. This type of inheritance results in a range of phenotypes due to the additive effects of many different genes working together.
What inheritance pattern best explains how genes influence human height?
Human height is influenced by multiple genes, making it a polygenic trait. The pattern of inheritance is more complex than simple Mendelian traits, as height is continuously variable and influenced by environmental factors as well. This fits with the idea of polygenic inheritance.
When a trait has more than two alleles how is the trait inherited?
When a trait has more than two alleles, it can be inherited in various ways depending on the interaction of the alleles. Multiple alleles can exist at a single genetic locus, and the specific inheritance pattern is determined by factors like dominance, recessiveness, and co-dominance. Each individual can still only inherit two alleles for a specific gene, but the presence of multiple alleles can create a wider range of possible genotypes and phenotypes.
