In sexual reproduction, a single specialized cell from a female merges
with a specialized cell from a male. As the fertilized egg, carrying genetic
information from each parent, multiplies to form the complete organism
with about a trillion cells, the same genetic information is copied in
each cell.

Life Science: Reproduction and heredity Grades 5-8, page 157 In many species, including humans, females produce eggs and males produce sperm. Plants also reproduce sexually--the egg and sperm are produced in the flowers of flowering plants. An egg and sperm unite to begin the development of a new individual. That new individual receives genetic information from its mother (via the egg) and its father (via the sperm). Sexually produced offspring never are identical to either of their parents.
