Frequently Asked Questions
What is the difference between mitosis and meiosis in reproduction?
Mitosis produces identical copies of cells for growth and repair. Meiosis is a special division in testes and ovaries that produces gametes (sperm and eggs) with half the chromosome number. This is why fertilization restores the full chromosome number.
Can a woman become pregnant without menstruation?
No, menstruation indicates the uterine lining is prepared for pregnancy. The hormonal changes that produce menstruation also prepare for potential pregnancy. However, some women have irregular cycles, and fertility issues can affect menstruation.
Why is the first trimester considered the most critical period of pregnancy?
During the first trimester, the major organs and body structures develop. This is when the developing embryo is most vulnerable to damage from infections, medications, and unhealthy behaviors. Most miscarriages occur during this period.
