Principle of Inheritance and Variation Biology Note online Class 12   What is Heredity? Heredity is the process by which inherited characteristics are passed on from parents to their children. Genetics is a branch of biology dealing with principles and processes of inheritance and variation. Inheritance is the foundation of heredity, and it is by this mechanism that traits are passed on from parents to offspring.   Heredity refers to the transfer of traits from parents to their offspring through asexual or sexual reproduction. These traits or characteristics are present on the chromosomes in the form of genes.   Genes, which are located on chromosomes, are the fundamental unit of inheritance, and the difference between individuals of the same species is unavoidable. The expression of genes on chromosomes varies due to chromosome crossing, recombination, mutation, and environmental factors.   What is Inheritance? What is a variance? The system of transferring characters from parent to o

Trigonometry Formulas Important Trigonometry Formulas -  Live Class Trigonometry is the branch of mathematics which deals with phenomenon related to height and distance. sine, cosine, and tangent are the basic and main functions of trigonometry. Trigonometry is basically derived from the Greek word where trigonon means “triangle” and metron means “measure”. The trigonometric functions include the following 6 functions: sine, cosine, tangent, cotangent, secant, and cosecant . For each of these functions, there is an inverse trigonometric function. The trigonometric functions can be defined using the unit circle. In class 10th, there are basically three trigonometric identities, which we learn in the trigonometry chapter. They are: Cos2 θ + Sin2 θ = 1.
