No, not all fertilized eggs survive. Natural processes and genetic abnormalities can lead to early developmental failures. Factors like chromosomal anomalies and environmental conditions also play a role in this early attrition, making it a common aspect of reproduction.

FAQs & Answers

  1. Why don’t all fertilized eggs survive? Many fertilized eggs fail to survive due to natural processes such as chromosomal abnormalities and unfavorable environmental conditions that affect early development.
  2. What causes early developmental failure in embryos? Early developmental failure can be caused by genetic mutations, chromosomal anomalies, and environmental factors that disrupt normal embryo growth.
  3. Is it common for fertilized eggs to not develop into embryos? Yes, it is common due to the body's natural selection process eliminating embryos with abnormalities to increase the chances of a healthy pregnancy.
