Many polygenic traits are represented by a bell cure because they are controlled by many genes and result in gradations where each gene has an effect.

Traits that are shaped by many genes are called what?
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
Why is there a wide range of phenotypes in polygenic inheritance?
"polygenic inheritance"- the inheritance of quantitative traits, traits which are influenced by multiple genes. Polygenic inheritance shows how multiple genes in combination with a person's environment can influence someone's phenotype, or physical appearance. A wide range is produced because the gene combinations are vast.
What are Mendelian traits?
Traits that are controlled a multiple gene loci. Polygenic traits.
What are traits due in part to multiple loci?
POLYGENIC
The study of how traits are inherited through the interactions of alleles is?
Polygenic inheritance

Define and distinguish between pleiotropy and polygenic inheritance?
Pleiotropy: one gene affects many traits (phenotypes) Polygenic: many genes affect one trait (phenotype)
What is trait called when it is controlled by more than one gene?
Polygenic Traits
Traits controlled by two or more genes are called what?
Polygenic Traits.
How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
Why certain polygenics traits represented by a bell curve?
Many polygenic traits are represented by a bell cure because they are controlled by many genes and result in gradations where each gene has an effect.
What can polygenic inheritance can explain?
Polygenic inheritance is a reason for some of the variety in human appearance. Eye color, hair color and skin color are all polygenic traits. That is why there are dozens of possible eye colors instead or just two or three. The mixing of alleles from multiple genes increases the number of possible phenotypes.
How is pleiotropy different from polygenic inheritance?
Differencebetween polygenic and pleiotropic traits
Trait controlled by two or more genes?
Polygenic Traits
What are Mendelian traits?
Traits that are controlled a multiple gene loci. Polygenic traits.
