Would human skin color be an example of a multifactorial trait or a polygenic trait? Technically, polygenic traits are not influenced by environmental factors, while multifactorial traits are and skin color can be influenced by the sun(an environmental factor). But every source gives skin color as an example of a polygenic trait? What actually is skin color? Multifactorial or polygenic?

The internet says they're the same thing; when I went on Wikipedia, they both redirected to quantitative trait loci.

I would say that it's polygenic.

Technically, it could be influenced by the sun, but that's not permanent.

What sort of questions would they ask about epistasis and multifactorial traits on a Nationals test?

Is there still going to be a Heredity event next year?

No there will not be

However, there will be Bio-Process Lab next year which consists of some Genetics. Topics on DNA, RNA, Punnett squares, genotype and phenotype ratios, chromosomal deficiencies will be taught. A majority of Bio-Process Lab will be on 9th grade biology.

Sure, Heredity doesn't rotate out. Eat your words...
