Answer

Brief Explanations:

For Question 1, superfecundation is when multiple sires contribute to a single gestation, common in species with litters like dogs. Polyparental is not the correct term here. Superfetation is the fertilization of a new oocyte during an existing pregnancy. Polyspermatic is not the right term for this concept. For Question 2, mares usually ovulate 24 hours before the end of estrus. This is a well - known fact in equine reproductive physiology.

Answer:

Question 1: C. superfecundation Question 2: A. 24 hours before the end of estrus
