Final answer:
Gametes are composed of material derived from both parents.
Step-by-step explanation:
Gametes are specialized reproductive cells that are responsible for sexual reproduction. They are produced by a type of cell division called meiosis, which results in cells with half the number of chromosomes as the original cell. The fusion of two gametes during fertilization restores the full chromosome number and gives rise to a new organism.
Gametes are haploid cells that are composed of material derived from both parents. In animals, sexually reproducing adults form haploid gametes from diploid germ cells. Fusion of the gametes gives rise to a fertilized egg cell, or zygote, which will undergo multiple rounds of mitosis to produce a multicellular offspring.
