Meiosis II
Give this one a try later!
The second division of a two-stage process of cell division in sexually
reproducing organisms that results in cells with half the number of
chromosome sets as the original cell
,Locus (plural: loci)
Give this one a try later!
A gene's specific location along the length of a chromosome
What is most DNA of a eukaryotic cell packaged into to make it more compact?
Give this one a try later!
Chromosomes
Shortening of telomeres way contribute to _____
Give this one a try later!
The aging process
What scientists are credited for discovering the double helix shape of DNA?

,What happens to gametes when nondisjunction occurs?
Give this one a try later!
One gamete receives two of the same type of chromosome and another
receives no copy. The other chromosomes are usually distributed evenly
What stage does "crossing over" occur?
Give this one a try later!
Prophase 1
