Although all genetic diversity originates as a mutation there are two mechanisms that occur during meiosis that can recombine ex
isting 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 answer for the given question above about a cladogram showing the evolutionary relationships between different vertebrates is option A. <span> Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds. I hope this helps.</span>
