Explain how chordates reproduce

Explain how chordates reproduce?

E

Expert

Verified

The reproduction in beings of phylum Chordata is sexual, with the exemption of urochordates which can as well reproduce asexually. In certain classes (that is, osteichthyes fishes, cyclostomes, and amphibians) there is larval phase. With rare exceptions, amphibians, fishes, reptiles and monotreme mammals are oviparous, egg-laying (that is, embryos develop in eggs and exterior to the mother’s body) and marsupial and placental mammals are viviparous (that is, embryos develop within the mother’s body, feeding from her).
