An unfertilized egg is produced by a female and does not contain a genetic contribution from a male. A fertilized egg results when a male's sperm successfully merges with the female's egg, beginning the process of embryo development.

FAQs & Answers

  1. What happens to an unfertilized egg? An unfertilized egg does not develop into an embryo and is typically expelled from the female body during the menstrual cycle.
  2. How does fertilization begin embryo development? Fertilization occurs when a male's sperm merges with the female's egg, triggering cell division and the start of embryo development.
  3. Can an unfertilized egg develop into a baby? No, an unfertilized egg lacks the genetic material from a male and cannot develop into a baby on its own.
