Question

Quizplus · Accepted Answer

Animals that produce litters have adaptations to support multiple offspring at once, including a uterus with more implantation sites, more nipples and mammary gland tissue for feeding, and the triggering of more eggs to develop. The tendency to have identical twins from the division of the fertilized egg is less directly related to litter size and more to genetic or species-specific reproductive strategies. However, all these factors can contribute to the ability of an animal to produce and care for a litter.
