Parental traits are transferred from one generation to other generation by means of chromosomes, DNA, or Genes.
Mendel’s Laws of Inheritance
On the basis of his experiments of hybridization Mendel proposed following rules of heredity-1. Law of dominance, 2. Law of iseggregation and , 3.Law of Independent Assortment.
Human Reproductive Health
The physical and mental conditions that collectively affect the reproductive capacity of a male or a female are called as reproductive health. The reproductive health is most essential for reproduction.
Population Control
Through different means – natural and unnatural the process of keeping in a limit the growth of population is called as Population Control. It is essential for the welfare of human families. This is the reason why its name has been changed to the Family Welfare.

The early man started his life as an individual. Gradually he came in contact with his fellows and he started developing a social life. At any period of human life it is hard to understand that a man ever remained in isolation. Thus this hypothesis does not cover the whole thing.
Technological Models
Recently, it has been found that Photo Voltaic Cells cannot be popularly used for power generation on large scales. However, our scientists have discovered that the alignment of Carbon Nano Tube with the polymer composites substrate would give very high efficiency in Photo Voltaic Conversion.
