PLZ HELP! WILL CHOOSE BRAINLIEST! Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II? fertilization

independent assortment

crossing over

chromosome replication

Crossing over

Explanation;

-Meiosis is the type of cell division that takes place in the germ line cells which results in the production of haploid cells called gametes.

-One of the advantage of meiosis is that it results to genetic variation thus creating genetically unique reproductive cell types. Genetic variation occurs due to the process of cross over in which homologous chromosomes exchange genetic materials through the chiasmata. It involves the exchange of segments of chromosomes between non sister chromatids.

weathering is the answer.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
