Answer 2

Sexual Reproduction in Animal​s

It occurs in following steps:

• Sperms or male gametes are produced by male parent and sperm contains long tail i.e. flagellum for movement.

• Ova, eggs or female gametes are produced by female parent which is a bigger cell than the sperm having a lot of cytoplasm.

• The sperm enters in to the ovum or egg and fuses to form a new cell called ‘zygote’. This process is known as fertilisation. So, the zygote is fertilized ovum.

• The zygote then divides again and again to form a large number of cells, ultimately grows and develops to form a new baby.

• Fertilization of an ovum or egg by a sperm to form a zygote.

Advantages of Sexual reproduction:

• The Sexual reproduction has many advantages over asexual reproduction. In asexual reproduction, the offspring produced is almost identical to their parent because of same genes. So, much genetic variation is not possible. This is a disadvantage as it inhibits the further evolution of the organism.

• In Sexual reproduction the offsprings although similar to their parents, are not identical to them or to one another. Because the offsprings receive some genes from the mother and some from the father. So, mixing of genes makes various different combinations and so all the offsprings have genetic variations. In this way sexual reproduction leads to a greater variety in population i.e. species can adapt more quickly to changes in its surroundings or environment.

• We can say that sexual reproduction promotes diversity of characters in the offsprings by providing genetic variation. Sexual reproduction plays an important role in the origin of new species having different characteristics. This genetic variation continuous leads to the evolution of species to form a better and still better organism which is not possible in asexual reproduction.
