. Explain the two ways by which the embryo inside the eggs of oviparous can undergo complete development
Answers
Explanation:
Animals that lay eggs are called oviparous. In oviparous animals, fertilization takes place internally but embryo development takes place externally.
The eggs of birds such as hen and duck carry immature embryo in them. The hard shells of eggs protect them from damage. Once the fetus is matured, the egg hatches. The trait of egg-laying animals is known as oviparity.
Examples of Oviparous Animals
All birds lay eggs with a typical hard calcium shell. Frogs are egg-laying amphibians which have soft gelatinous eggs requiring constant hydration. Almost all fishes are oviparous. Except for some species of snakes, all other reptiles are oviparous. In mammals, Echidna and platypus are egg-laying.
Fertilization takes place internally but embryo development takes place externally are two ways by which the embryo inside the eggs of oviparous can undergo complete development
Explanation:
- Oviparous animals are beings that lay their eggs, with limited or no other embryonic growth within the mother.
- This is the generative method of most fish, all birds, reptiles, amphibians, and the monotremes.
- Being oviparous is an evolutionary approach for a generation. In this approach, one or many eggs can be delivered.
- Each embryo is a gamete that has the female’s enrichment of the genetic matter.
