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 is the difference between epistasis and polygenic inheritance in genetics?

Epistasis is when one gene affects the expression of another gene, while polygenic inheritance involves multiple genes contributing to a single trait. Epistasis involves the interaction between genes, while polygenic inheritance involves the cumulative effect of multiple genes on a trait.


How does polygenic inheritance differ from Mendelian inheritance?

polygenic inheritance is when more than one genes are responsible for a character/phenotype. for example human skin color. if one want to draw a pedigree for that, he will not be able to succeed. although individual genes at molecular level is inherited according to mendel's laws. and mendelian inheritance simply follows mendels laws. also the character is controlled by one gene only. for example pea plant height.


Polygenic inheritance can explain?

Polygenic inheritance is a trait where multiple genes are being used. ex. Height: your neither "short" or "tall" your somewhere in the middle. It's not like pea plants where you are either tall or short. You are a variety. When graphing polygenic inheritance, you will find that there is a bell curve because there are man heights in between tall and short.


What would be your clue that a character would have polygenic inheritance pattern?

Well, honey, if you see a trait that's controlled by multiple genes, each with small effects, then you might be dealing with polygenic inheritance. So, keep an eye out for characteristics like height or skin color that show a wide range of variation in a population. And remember, genetics can be a real mixed bag, just like my collection of ex-husbands.

The color of wheat grains shows variability between red and white with multiple phenotypeswhat is the inheritance pattern?

The inheritance pattern of wheat grain color showing variability between red and white with multiple phenotypes is most likely controlled by multiple genes, exhibiting polygenic inheritance. This means that the trait is influenced by the combined effects of multiple genes, leading to a continuous range of phenotypes rather than distinct categories.

What are the differences between epistasis and polygenic inheritance in terms of their impact on the expression of traits?

Epistasis occurs when one gene masks the expression of another gene, leading to a specific trait being completely hidden. Polygenic inheritance involves multiple genes contributing to a trait, resulting in a more continuous range of expression. Epistasis has a more direct and immediate impact on trait expression, while polygenic inheritance leads to a more gradual and varied expression of traits.


What is the interactive nature of polygenic genes?

Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well.

What is one difference between a single gene trait and a polygenic trait?

Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by mulitple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.


Do all traits exhibit exhibit classic Mendelian inheritance?

No, not all traits exhibit classic Mendelian inheritance. Many traits are influenced by multiple genes and environmental factors, leading to more complex inheritance patterns. Additionally, traits such as height, skin color, and intelligence are polygenic and multifactorial in nature, meaning they are influenced by multiple genes and environmental factors.


What are the key differences between Mendelian genetics and non-Mendelian genetics in terms of inheritance patterns?

Mendelian genetics follows predictable patterns of inheritance based on dominant and recessive alleles, while non-Mendelian genetics involves more complex inheritance patterns such as incomplete dominance, codominance, and polygenic inheritance. Mendelian genetics is based on the principles discovered by Gregor Mendel, while non-Mendelian genetics includes variations that do not strictly follow Mendel's laws.
