Sexual reproduction is the most common form of reproduction in the animal kingdom and is the only reproduction type in humans.
With over seven billion humans on Earth, there is an enormous variation in genetics within the human population. Which
statements describe how cell division and sexual reproduction contribute to this huge genetic variation? Select ALL that apply.
A)
B)
Random fertilization of haploid eggs by many potential haploid sperm
increases genetic variation
Increased frequency of mitotic division ensures that animals have cells to
replace those that are lost.
The ability of homologous chromosomes to swap and exchange gene
regions in meiosis contributes to genetic variation.
Random assortment of homologous chromosomes in metaphase I increases
the variation of chromosomes that segregate into gamete cells in meiosis.
Increased chromosome number at the end of meiosis ensures that resulting
offspring have additional chromosomes containing increased genetic
variation
D)
E)
