Genetics

a form of a gene apex

One of the major aspects of life is self replication, or reproduction. If cells didn't divide, then populations of organisms would not form, and evolution would be impossible. The more proximate cause is that as cells grow and ingest food, there is a limit to how big they can become before the cell wall no longer supports the cytoplasm. At or before this point, the cell must divide or it will lyse (split open) and die.

the chromosomes are duplicated.

DNA doubles and produces sister chromatids before meiosis begins.

the chromosomes must replicate

a sperm or egg cell produced by meiosis

A heterozygote is an organism with two different alleles for a trait.

Yes. (:

Sexual reproduction joins two cells that each have half the total chromosome number.

Tetrad

The name for different forms of a gene is allele.

>A< (A.S.Apex approved :P)

G2

Which would most likely decrease the genetic variation in the human population?

because he had the things to

two forms of the trait are both equally dominant

The factors for each trait are separated independently when sex cells form.

how traits are passed to offspring

he crossed two pure lines

it dominates the phenotype

He tested seed color and shape at the same time.
