Which series lists the stages of development in the gestational process in order, from beginning to end?
a) gametes ® embryo ® zygote ® fetus ® organism
b) gametes ® zygote ® embryo ® fetus ® organism
c) embryo ® gametes ® zygote ® fetus ® organism
d) zygote ® gametes ® embryo ® fetus ® organism

The correction option for the stages of development is gametes, zygote, embryo and fetus.

Gestation is the process in which an offspring develops inside viviparous. Firstly, male and female gametes fuse together to form zygote. Gametes are haploid (n) in nature. When they fuse together to form zygote which is diploid (2n). After the formation of zygote, embryo develops which is the early stage of development of a multicellular (contains more than one cell) diploid eukaryotic organism.

With the passage of time, embryo becomes fetus which is an unborn more than eight weeks after conception. Then fetus develops and then form an organism and finally it is hatched at the end.
