The Science of Inheritance.

Genetics is the scientific study of heredity and variation. As heredity deals with transfer of genes from parents to their offsprings, variation deals with the differences that exist between organisms of same species.

The factor responsible for the expression of traits and characters in living organism is known as genes. These genes are inherited from both parents as in s*xual reproduction. Some of these traits maybe physical for e.g. hair, eye and skin color. On the other hand, some traits are not visible but deals with the functionality of the organism e.g. blood groups.

The genetic information lies within the nucleus of each living cell. Inside the nucleus is a threadlike material that bears the info molecules known as 🧬 DNA and proteins (histone). The segment of this DNA molecule is the gene. The DNA carries the basics unit of Inheritance called genes which can be recessive or dorminant.

Humans have 23 pairs of these small threadlike structures in their somatic cells hence are called diploid i.e. complete set of chromosomes (2n) organisms. One set of these chromosomes is found in their reproductive cells e.g. s***m and eggs hence are haploid i.e. one set of chromosomes (n).

During reproduction, these gametes (s*x cells) fuse together through a process of fertilization to form a zygote ( a fertilized) which grows mitotically and express the information contained within its nucleus. This restores the diploid state of humans.
