Hardy-Weinberg’s Principle

Hey All AIPMT Biology Aspirants, learn about Hardy-Weinberg’s principle, which is one of the four major evolutionary process, apart from Gene Flow,Genetic drift and Natural selection, important for AIPMT Biology.

Hardy-Weinberg’s principle says that allele frequencies in a population are stable and is constant from generation to generation.

  • For applying algebraic equations of Hardy–Weinberg

Introduction to Genetics

Hello All AIPMT Biology Aspirants, here is the study material of Genetics.

  • Genetics: It is the science of heredity and variation.
  • Heredity: Transmission of traits from parents to offspring via genetic information.
  • Variation: In biology, the occurrence of differences among individuals.
  • Character: Heritable feature/ attribute that varies among individuals is called character,

Layers of Digestive Tract

Tissues of Digestive Tract

Hello All AIPMT Biology Aspirants, here is the study material of Layers of Digestive Tract.

Mammals and other vertebrates contain four major layers from lower esophagus to anal canal. These are Mucosa, Submucosa, Muscularis, and Serosa from innermost to superficial, respectively.

Three types of Salivary Glands

Salivary Glands

Hello All AIPMT Biology Aspirants. Next in the queue of study material is SALIVARY GLANDS.

Salivary glands release a secretion called Saliva into the oral cavity. Secretion of saliva is called Salivation which keeps the mucous membranes of buccal cavity moist and lubricates the movements of the tongue and lips during

Mechanism of Digestion

Digestion is a process of breaking down larger insoluble food particles into smaller water-soluble molecules that can be easily absorbed by the body cells.

  • Alimentary canal/Digestive tract/ Gastrointestinal (GI) tract is a continuous tube from mouth to anus.
  • Six basic processes performed by digestive system are:
    1. Ingestion: Taking

Mendel’s Success Story

Hello All AIPMT Biology Aspirants, next important topic in queue is Mendel’s Success Story.

Earlier, plant biologists also produced hybrids but they saw puzzling results and were not able to interpret them correctly. Mendel used mathematical techniques to analyze his crosses, which was ahead of that time and people were not
