  • The embryonic development takes through several developmental stages.
  • The sperm and ovum fuse to form the zygote. 
  • The zygote undergoes mitotic cleavage to form morula which is a 16 celled stage known as the morula which further divides to form blastula which is 128 celled stage. 
  • The blastula differentiates into gastrula which is cup-shaped and has three germ layer cells which further forms an embryo and undergo organogenesis.
