Reproduction in Animals Test - 1

Zygote is produced during sexual reproduction. It is a eukaryotic cell formed by a fertilization event between two gametes.

Among these, humans show viviparity as they give birth to young ones.

The Oviduct is the tube that links the ovary to the uterus and which the ovulated oocyte travels down to become fertilised by sperm present in the female tract. It is also refered to as the Fallopian tube, Uterine tube or Ovarian tube.

Viviparity is found in rabbit as it is a viviparous animal which give birth to living young that have been nourished in close contact with their mothers' bodies.

In sexual reproduction, there must be a union of one male and one female reproductive cell.

When male differs from female in morphology, it is called sexual dimorphism. This differentiation happens in organisms who reproduce through sexual reproduction, with the prototypical example being for differences in characteristics of reproductive organs.

When larvae develops gonads and reproduces by normal sexual reproduction, it is called neoteny.For example, the adult axolotl, a salamander, retains larval external gills.

Anisogamy is found in human beings, earthworms and pilas.Anisogamy refers to a form of sexual reproduction involving the union or fusion of two dissimilar gametes .The smaller gamete is considered to be male (sperm cell), whereas the larger gamete is regarded as female (egg cell).

The developing embryo does not receive nourishment from mother's body in oviparous reproduction.

Complete metamorphosis is found in butterflies.It is insect development in which egg, larval, pupal, and adult stages occur, each differing greatly in morphology.
