Why is Vivipary advantageous?
Viviparity (give birth to live young) is good because the embryo can develop inside the mother where temperatures and nutrients are stable, thus enabling the young a greater chance to survive. This is especially true in cold weather.
Why is viviparity advantages over oviparity?
Answer: Explanation: Another important benefit of viviparity is the ability to reproduce at any time of the year. Unlike oviparous animals, which must produce yolk sacs when their food intake is the highest, viviparous animals can nourish their young with fat reserves.
What is the most advantageous for developing animals oviparity?
The young one gets better nourishment and good shelf life. They have their own system. They produce the young one instead of egg. Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild.
What is the disadvantage of viviparity?
The main disadvantage of viviparity is that the female is more vulnerable to predation during gestation and can only have one clutch a year as gestation can last from 1.5 to 6 months.
What is the animal of oviparity?
Oviparous animals are female animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes.
What is the difference between oviparity and?
The key difference between oviparity ovoviviparity and viviparity is that oviparity is the trait of laying eggs, while ovoviviparity is the development of embryos inside eggs that are retained within the mother’s body until they are ready to hatch, and viviparity is giving birth to young ones directly.
What are the advantages of ovoviviparity over oviparity?
Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild. A disadvantage of ovoviviparity is that fewer individuals are born and it takes more emery for the females to carry the eggs inside.
What is viviparity and oviparity?
Oviparity is generally defined as “any spawning of oocytes (unfertilized) or fertilized eggs” and viviparity is defined as “any mechanism for live-bearing or maintenance of development, by either maternal or paternal parent in or on any part of the body”, while ovo-viviparity straddles both modes [15].
What is oviparity in biology?
oviparity, expulsion of undeveloped eggs rather than live young. The eggs may have been fertilized before release, as in birds and some reptiles, or are to be fertilized externally, as in amphibians and many lower forms.
What is the difference between oviparity and over?
This means oviparous animals lay eggs. These eggs develop and hatch into young individuals. In contrast, viviparous animals are born as live young individuals. Therefore, they do not lay eggs.
