Question

Which of the following statements isTRUEbased on the disadvantages of sexual and asexual reproduction?

A
Gametogenesis is the only source of genetic variation for sexual reproduction
B
Crossing over is the only source of genetic variation for asexual reproduction
Mutations are the only source of genetic variation for asexual reproduction
D
Meiosis is the only source of genetic variation for sexual reproduction

Answer 1

D. Meiosis is the only source of genetic variation for sexual reproduction

Step-by-step explanation:

Sexual reproduction is the form of reproduction that involves two parent organisms which produce gametes or sex cells that unite while asexual reproduction involves only one parent to occur. One advantage of sexual over asexual reproduction is that there is room for genetic VARIATION among offsprings produced.

However, this genetic variation occurs in sexual reproduction as a result of a process called CROSSING OVER in MEIOSIS. Meiosis is the only division that produces gametes in living organisms and it only occurs in sexually reproducing organisms.
