Question

Which is a source of variation and genetic diversity that is shared between prokaryotes and eukaryotes?

• A. Random fertilization involving a unique sperm and a unique egg
• B. Independent assortment of each chromosome pair during metaphase I of meiosis
• C. Crossing-over during prophase I of meiosis
• D. Random mutation

Answer 1

The correct option is D Random mutation

The genetic material in prokaryotes is not confined into a nucleus and they do not have a nuclear membrane and the genetic material is present in the form of chromatin and cytoplasm and there is no chance of crossing over during meiosis and no fertilization but random mutations do arise in them and it results change in the genetic material.

So, the correct option is 'Random mutation'
