Hi, here's some differences between unfertilized and fertilized eggs.
A fertilized egg is only formed when the fusion of a haploid female gamete mates with a male haploid gamete.
A Unfertilized egg hasn't been touched by a male gamete.
Fertilization happens to form the fertilized egg
Unfertilized egg doesn't have to undergo fertilization to be formed
A fertilized egg is always developed into a diploid organism
A unfertilized egg can sometimes produce a haploid organism
Fertilized eggs are formed during the sexual reproduction
Asexual production forms offspring for unfertilized eggs.
Hope this was helpful, let me know if you need more help :)
