Question

Genetic mutations in asexually reproducing organisms lead to more evolutionary change than do genetic mutations in sexually reproducing ones because _____.
a) asexually reproducing organisms devote more time and energy to the process of reproduction than do sexually reproducing organisms.b) asexually reproducing organisms, but not sexually reproducing organisms, pass all mutations to their offspring.c) sexually reproducing organisms can produce more offspring in a given time than can sexually reproducing organisms.d) more genetic variation is present in organisms that reproduce asexually than is present in those that reproduce sexually.e) asexually reproducing organisms have more dominant genes than organisms that reproduce sexually.

Answer 1

Answer:

The correct answer is b) asexually reproducing organisms, but not sexually reproducing organisms, pass all mutations to their offspring.

Explanation:

In asexually reproducing organisms all the mutation is passed to the offspring so the offspring are identical to the parents. Daughter cells contain all the genes that are present in the parent, therefore, in asexually reproducing organisms mutation leads to more evolutionary change.

In sexual reproduction, the offspring get half genes from male parents and half from female parent so a parent does not pass all the mutation in the offspring and in sexual reproduction selection pressure eliminate those offspring that have bad mutation so that the wrong mutation can not pass to next generation.

Therefore the correct answer is b.
