Question

What creates genetically different offspring in both asexual and sexual reproduction?

a) Mutations.
b) Mitosis.
c) Meiosis.
d) Mutations and mitosis.
e) Mitosis and meiosis.

Answer 1

Genetically different offspring in asexual and sexual reproduction are created mostly through mutations in asexual reproduction, and through genetic recombination and mutations in sexual reproduction. The correct option is a) Mutations.

Step-by-step explanation:

The creation of genetically different offspring in both asexual and sexual reproduction can be attributed to mutations. In asexual reproduction, which often involves mitosis, the offspring are typically clones of the parent. However, spontaneous mutations in the DNA can introduce genetic variation.

Sexual reproduction, involving meiosis, naturally creates variation through the shuffling of genetic material between two parents during the formation of gametes, the crossing over during prophase I, and the random assortment of chromosomes during metaphase I.

This genetic recombination, along with mutations, contributes to the genetic diversity seen in sexually reproducing populations. The correct option is a) Mutations.
