Question

which characteristic of eukaryotes is fundamental in leading to enormous genetic diversity among eukaryotic organisms?
a) the fact that eukaryotes can be multicellular
b) the ability of eukaryotes to compartmentalize chemical reactions
c) the ability of eukaryotes to sexually reproduce
d) the presence of a nucleus in eukaryotes

Explanation:

Sexual reproduction in eukaryotes involves processes like meiosis, which leads to genetic recombination through crossing - over and independent assortment of chromosomes. This results in new combinations of alleles and thus enormous genetic diversity. Multicellularity, compartmentalization of reactions, and the presence of a nucleus do not directly contribute to genetic diversity in the same fundamental way as sexual reproduction.

Answer:

C. the ability of eukaryotes to sexually reproduce
