.5 - 3mm per minute to reach the site. The fertilisability of human sperm in the female genital tract is of 12 - 24 hrs while they survive upto 3 days. Since the ovum is non motile and the energy content of the sperm is low, the sperm must approach the egg as quickly as possible. So it is..

This is another deviation of reproductive strategy in which an unfertilised ovum, without the process of fertilisation transforms into a new individual. Rotifers, some molluscs, arthropods, etc. take up parthenogenesis as a natural form of reproducti..

Fertilisation is the fusion of the female gamete (Egg or Ovum) produced in the embryosac and the male gamete produced in the pollen tube by the pollen grai..

Meiosis is a cell division occurs in reproductive cells (gametes). The male gamete is known as the sperm in animals and the female gamete is known as the ovum (egg..

Cleavage is an unique embryological process which transforms the single fertilised egg cell into a sphere of closely aggregated multitude of cells. Immediately after fertilisation the fertilised ovum (egg cell) undergoes a series of cell divisions. These divisions are called cleavag..

In this type, the females have two homomorphic sex chromosomes XX and hence they are homogametic. The males have one sex chromosome and are represented as XO. If the X-carrying ovum is fertilised by a X-carrying sperm, the resulting zygote XX will develop into a female. If the sperm carry..

The sperm generally comes in contact with the ovum at the animal pole. A number of sperms surround the ovum, but only one of them fuses with the egg. Fertilisation of the egg with only one sperm is known as monospermy. Fertilisation occurs in the ampulla of the oviduc..
