Interesting Facts about Genetics

What Is Genetics?

Genetics is the branch of biology, which mainly deals with the study of the gene, genome, nucleus, DNAand genetic inheritance.

The word genetics was introduced during the1900’s by English biologist William Bateson. James D Watson and Francis Crick were the first people to discover both the model and the structure of the DNA molecule in the year 1953. Genetics is a theoretical structure, which is mainly used to understand the different biological processes, the study of genes, cell cycle, heredity, gene structure, inherits genes and much more.

Gregor Johann Mendel is known as the “Father of Modern Genetics”. Based on his discoveries and experiments on the basic principles of heredity, today we are able to learn about heredity and how genetic traits are passed on from parents to offspring?

Let us learn some interesting facts about Genetics.

Facts about Genetics


Chromosomes are known as the genetic material of an organism, which is composed of proteins and DNA molecules. Altogether, a newborn baby has 23 pairs of chromosomes and are entirely inherited or transferred from their parents. The 23rd pair of a chromosome is called the sex chromosome, which helps in the determination of sex of an individual.


Every single living organism, including animals, birds, plants and other species, comprises the same DNA molecules and are composed of four similar chemical nucleotides, the basic building block of nucleic acids.


In genetics, we will learn more in detail about the genes, differences in the shape and size of all DNA molecules.

The origins of genetics lie in the development of theories of evolution. The study about the gene, genome, chromosomes, DNA, started decades ago.


According to human evolutionary genetics studies, it describes the evolution of man, the evolution of brains, as well as how one human genome differs from another human genome.


In all living organisms, a single variation in a gene results in several health disorders and is called as genetic disorders.


According to Mendel’s law of inheritance, there are different types of genetic disorders and can be easily determined from the pedigree analysis. All these disorders are inherited from parents to their offspring.

The study of Genetics explains mainly how the diseases are inherited in the family. The study of genomics plays an equal and vital role in studying about health and diseases. Both Genetics and genomics helps to analyze and examine why some people are more prone to various infections, while others are not.
