Detailed explanation-1: -When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment. It results in gametes that have unique combinations of chromosomes.
Detailed explanation-2: -The law of independent assortment states that the random orientation of homologous chromosome pairs during metaphase I allow for the production of gametes with many different assortments of homologous chromosomes.
Detailed explanation-3: -What term is used to describe the way homologous pairs of chromosomes line up at random orientation during Metaphase I? Independent assortment; daughter cell randomly inherits either the maternal or paternal chromosome from each pair.
Detailed explanation-4: -Definition. The random organisation of chromosomes in the middle of the cell during the first stage of meiosis, which further increases genetic diversity.
Detailed explanation-5: -The orientation is random, with either parental homologue on a side. This means that there is a 50-50 chance for the daughter cells to get either the mother’s or father’s homologue for each chromosome. Chiasmata separate. Chromosomes, each with two chromatids, move to separate poles.
