How do I use statistics and probability to analyze the effects of environmental factors on the expression of traits? Please this is due today and i didnt watch the video

You'll often hear a teacher use a human trait as an example in a genetics problem, ... Unlike Mendel's pea plants, humans don't come in two clear-cut “tall” and ... hard to distinguish the effect of each individual gene, and even harder to see that ... just depend on genetics: it also depends on environmental factors

Explanation:

HS.LS1.A: Structure and Function

All cells contain genetic information in the form of DNA molecules.

Genes are regions in the DNA that contain the instructions that code

for the formation of proteins. (HS­LS3­1)

DCI: Heredity: Inheritance and Variation of Traits

HS.LS3.A: Inheritance of Traits

Each chromosome consists of a single very long DNA molecule, and

each gene on the chromosome is a particular segment of that DNA.

The instructions for forming species’ characteristics are carried in

DNA. All cells in an organism have the same genetic content, but the

genes used (expressed) by the cell may be regulated in different

ways. Not all DNA codes for a protein; some segments of DNA are

involved in regulatory or structural functions, and some have no asyet known function. (HS­LS3­1)

HS.LS3.B: Variation of Traits

Explanation:

In sexual reproduction, chromosomes can sometimes swap sections

during the process of meiosis (cell division), thereby creating new

genetic combinations and thus more genetic variation. Although DNA

replication is tightly regulated and remarkably accurate, errors do

occur and result in mutations, which are also a source of genetic

variation. Environmental factors can also cause mutations in genes,

and viable mutations are inherited. (HS

eukarya because is is like alche and b is bacteria and d is animals

explanation:

helicase, i think thats it
