6. Complete the statement about genetic variation.
Meiosis contributes to genetic variability when
the chromosomes line up randomly during
metaphase 1 anaphase 1 prophase I. This
random line-up means that when the cell divides,
the number of chromosomes in each cell is the
same, but the contents are not. This process is
called independent assortment gene linkage
crossing over. During meiosis, gene linkage
independent assortment crossing over increases
genetic variation because it shuffles portions of
chromosomes around.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
