Zygote is the first result formed after fusion of male and female gametes i.e. sperms and egg respectively .
Fertilization in humans complete in 3 steps :
1)Acrosomal reaction
2)Cortical reaction
3)Amphimixis
Acrosomal & cortical reactions include the breaking of membranes of egg by the sperm for its entry .
Amphimixis stage include Zygote formation . Male & female nucleus fuse to form Synkaryon or Zygote .
Gametes are haploid in nature i.e only set of chromosomes are present . Fusion makes the combination of both chromosomes makes the zygote diploid . Further growth of zygote to human body has a diploid nature only .
