Summary Introduction
To describe: The process of fertilization in echinoderms and to point out some ways in which mammalian fertilization is different from it.
Introduction: Fertilization is the process of fusion of male and female gametes to form a zygote. The process of fertilization has evolved over time, and hence higher organisms have a different method of fertilization as compared to that of lower organisms. This difference is also due to differences in gametes of different organisms.
