Answer:
There is a difference in the types of fertilization among animals because of the female body structure. Depending on the variety of species, there are differences in the uterus of a female animal. Fertilization occurs when a sperm cell meets an egg cell in the fallopian tube. For example, in mammals, the newly fertilized cell is called a zygote. The zygote will pass through the fallopian tube going into the uterus. The zygote then sets into the uterus lining to support its embryo development.
