प्रश्न
Vivipary automatically limits the number of offsprings in a litter. How?

In viviparous animals (majority of mammals including human beings), the zygote develops into a young one inside the body of the female organism. After attaining a certain stage of growth, the young ones are delivered out of the body of the female organism. Vivipary automatically limits the number of offspring in a litter because female have limited space for the development of embryo.
