Questions and Answers

Why might small leaks that allow fetal blood to enter the mother's circulation be problematic?

  • The placenta may detach prematurely, affecting nutrient exchange.
  • The fetus may develop Rh-negative blood, causing health risks.
  • Maternal and fetal blood may mix, leading to complications.
  • The mother's body will produce antibodies to destroy fetal RBCs. (correct)
  • Why can a person with Rh-negative blood receive Rh-positive blood without issues?

  • Rh-negative blood lacks the Rh factor present in Rh-positive blood. (correct)
  • Rh-negative blood cells are more resilient to Rh-positive antibodies.
  • They naturally produce antibodies against Rh-positive blood.
  • Rh-negative blood contains factors that neutralize Rh-positive antibodies.
  • In the context of blood types, what does it mean for a trait to be autosomal recessive?

  • It is a trait that skips a generation.
  • It requires one gene from each parent for the trait to be expressed. (correct)
  • It is a trait only present in women.
