What are the characteristics of polygenic traits?
Polygenic means that multiple genes created the same trait. The skin color gene is polygenic because multiple genes will give you the same trait.
What are ways in which natural selection operates on ploygenic traits?
Polygenic? Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.
What are some yorkshire pig traits?
A Yorkshire pig has a few traits. Some of the traits are slim, pig and big.

In what ways are tunicates and lancelts similar to humans?
Tunicates and lancelets are common to humans in that all of them are chordates. That is they share certain charcteristics at some point in their lives. Four traits that they all share are notochord, hollow dorsal nerve chord, post anal tail, and pharyngeal gill slits. Some of these characteristics disappear during development, others are retained.
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.
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.
What are some polygenic traits?
Eye color, skin color... etc.
How is pleiotropy different from polygenic inheritance?
Differencebetween polygenic and pleiotropic 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.
Trait controlled by two or more genes?
Polygenic Traits
What are Mendelian traits?
Traits that are controlled a multiple gene loci. Polygenic traits.
How are polygenic traits controlled?
by two or more
How many genes must interact to produce a trait?
It depends on the trait. Some are Mendelian traits where there is one dominant and one recessive allele. Some traits are governed by multiple alleles, like blood groups, and some traits are governed by polygenic inheritance where several sets of genes determine the trait, like height in humans.
Traits that are produced by the interactions of several genes?
polygenic
What are traits due in part to multiple loci?
POLYGENIC
