Question

Mammals reproduce through a process called sexual reproduction. During this process, which involves two parents,

A. a female egg cell combines with a male sperm cell to make an offspring that is identical to one of the parents.

B. a female egg cell and a male sperm cell each develop separately into an offspring that is different from both parents.

C. a female egg cell and a male sperm cell each develop separately into an offspring that is identical to its parent.

D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents.

Answer 1

D- a female egg cell combines with a male sperm cell to make an offspring that is different from both parents

Step-by-step explanation:

Answer 2

D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents. Gametes are produced by meiosis, and the source of genetic variation during sexual reproduction comes from crossing over of tetrads at chiasma during prophase I, independent assortment, and random fertilization. These gametes (egg and sperm) then combine to form a genetically different offspring.
