Blood type AB in humans, for instance, is not a polygenic trait. Rather, it is a case of codominance. The two alleles for A and B antigens on the red blood cells of blood type AB individuals are dominant, and therefore are expressed together.

Which human trait is polygenic?
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.
What are 3 examples of polygenic traits?
Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
Are all traits polygenic?
Surprisingly, most traits in humans, and in fact most traits in most organisms, are polygenic. Mendelian traits, although we spend a lot of time talking about them, are really the exception. Most genetic characteristics or traits are controlled by many genes.
What is the opposite of a polygenic trait?
The correct option is D) pleiotropy. Polygenic inheritance is opposite to pleiotropy because pleiotropy is the phenomenon in which a single gene...
Which trait is polygenic in humans quizlet?
Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals. are those htraits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes.
How do you identify a polygenic trait?
Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.
What are the non-Mendelian inheritance?
Such modes of inheritance are called non-Mendelian inheritance , and they include inheritance of multiple allele traits, traits with codominance or incomplete dominance, and polygenic traits, among others. All of these modes are described below.
What are the type of non-Mendelian genetics?
Such modes of inheritance are called non-Mendelian inheritance, and they include inheritance of multiple allele traits, traits with codominance or incomplete dominance, and polygenic traits, among others, all of which are described below.
What is an example of a multifactorial trait?
Examples of Multifactorial Traits: Fingerprint patterns, height, eye color, and skin color...
Do humans have Mendelian traits?
In fact, most human traits are actually controlled by multiple genes, or otherwise have more than two alleles, which means they do not have a simple Mendelian inheritance pattern.
What are multifactorial traits?
What is multifactorial inheritance? Multifactorial inheritance is when more than one factor causes a trait or health problem, such as a birth defect or chronic illness. The main factor is genes. But the cause includes other factors that aren't genes, such as: Nutrition.
Is intelligence a polygenic trait?
Intelligence Is a Polygenic Trait
These findings show that intelligence is a highly polygenic trait where many different genes would exert extremely small, if any, influence, most probably at different stages of development.
What are polygenic traits quizlet?
polygenic triats. a trait that is controlled by several pairs of genes; different combinations of all the genes contribute to the trait in varying degrees. multiple allele traits.
What do people have 46?
Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.
Which are human traits determined by polygenic inheritance quizlet?
Human height, eye color, and hair color are examples of traits determined by polygenic inheritance.
