Population bottlenecks. but their genes still carry the marks of this bottleneck: they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted.
Because tropical levels used to be broken because temperatures hasn't varied in the years and history of global temperatures and history.
Recombination or crossing over occurs during prophase i. homologue chromosomes- 1 inherited from each parent pair along their lengths gene by gene. Independent Assortment is the process where the chromosomes move randomly to seperate poles during meiosis
sorry what this means¯\_(ツ)_/¯
