Although all genetic diversity originates as a mutation there are two mechanisms that occur during meiosis that can recombine existing genetic diversity into many trillion of new combinations what are these two mechanisms a. organization of DNA around histone molecules b. variability in the arrangement of Acton and meiosis molecules in the meiotic spindle c. Random assortment of alleles during metaphase one of meiosis d. telomeric shortening after successive rounds of cellular division e. Crossing over between homologous sister chromatids

option E is the correct crossing over between sister chromatids crossing over is important because it is a source of genetic variation and leads to different mutations (changes) in the body of zygote

The mechanism above described that can recombine existing genetic diversity during meiosis is the 'random assortment of alleles during metaphase I of meiosis' (Option c).

During the metaphase of meiosis I, the homologous pairs of chromosomes line up at the equator of the cell.

During anaphase I, these chromosomes are pulled toward opposite poles of the cell in order to form haploid cells, thereby the separation (i.e., assortment) of homologous chromosomes is random.

This process (i.e., independent assortment) results in a huge variety of possible genetic arrangements.

The crossing over between homologous non-sister chromatids represents another mechanism that can recombine existing genetic diversity during meiosis, but this option does not appear above.

Crossing over refers to the exchange of genetic material between non-sister chromatids during meiosis I (prophase I).

In conclusion, the mechanism that can recombine existing genetic diversity during meiosis is the 'random assortment of alleles during metaphase I of meiosis' (Option c).
