How does the sperm and ovum fuse?
A doctor has provided 1 answer
Chemically/hormonaly: A biochemical reaction occurs when the first sperm reaches the zona pellucida of the ovum that prohibits other sperm from entering. That first sperm subsequently sheds its cover and its dna is expanded inside the ovum so that the combination of the two haploid dnas can take place and create a brand new dna identity!
