2. Most animals have a diploid life cycle.
Most of the life cycle is spent in the diploid state (interphase).
All of the cells except the gametes are diploid.
A diploid germ cell in a reproductive organ goes through meiosis and forms gametes.
3. The gametes, the sperm and the egg, join during fertilization. The result is a diploid zygote.
This single diploid cell goes through mitosis and eventually gives rise to all of the cells of the adult, which are also diploid.
In diploid life cycles, meiosis in germ cells of a multicellular diploid organism results in the formation of haploid gametes.
