19051.	Question : Could the number of eggs or young ones produced by an oviparous and viviparous mother be equal?

Discussion

19053.	Question : Could the number of eggs or young ones produced by an oviparous and viviparous female be equal? Why?
Answer» Solution :No. The number of EGGS or young ONES produced by an oviparous and viviparous female cannot be equal. When the oviparous animals lay eggs in the external environment or in the medium, the chance of survival and successful development into the adults are not CERTAIN. But in case of viviparous animals, young ones are nurtured by the adult animals. Hence, oviparous animals lay more eggs if they are FERTILIZED in the medium or in water.

Discussion

19054.	Question : Could the number of eggs or young ones produced by an oviparous and viviparous mother be equal ? Why?
Answer» Solution :The NUMBERS of eggs produced by an oviparous mother will be more than the young ONES produced by a viviparous mother. This is because in oviparous ANIMALS the development of young ones takes place outside the mother.s body. Their eggs are more prone to environmental conditions and predators. Therefore, to overcome the loss, more eggs are produced by mothers so that even under harsh environmental conditions some eggs might be able to survive and produce young ones. On the other hand, in viviparous ORGANISMS the development of young ones takes place in safe conditions inside the body of the mother. They are LESS exposed to environmentar conditions and predators. Therefore, there are more chances of their survival and hence less number of young ones is produced compared to the number of eggs.
