Introduction Genetics, the study of genes, heredity, and variation in living organisms, has revolutionized our understanding of life. It explores how traits are inherited, how organisms evolve, and how genes interact with their environment. Beyond theoretical knowledge, genetics has profound practical applications in medicine, agriculture, biotechnology, forensic science, and research. Advances in genetic technologies are…

Genetic disorders are medical conditions caused by abnormalities in an individual’s DNA. These abnormalities can result from mutations, deletions, duplications, or rearrangements of genes or chromosomes. Genetic disorders affect millions of people worldwide, manifesting as mild conditions in some cases and severe, life-threatening illnesses in others. Understanding genetic disorders is crucial for diagnosis, treatment, prevention,…

Genetic variation is the diversity in gene frequencies within a population. It is the foundation of evolution and adaptation, allowing species to survive environmental changes, resist diseases, and develop new traits. Genetic variation arises from differences in DNA sequences among individuals and is influenced by processes such as mutation, recombination, and independent assortment. Studying genetic…

Introduction Chromosomes are fundamental structures within the nucleus of eukaryotic cells that carry genetic information in the form of DNA. They are essential for proper development, growth, and function in all living organisms. In humans, each cell typically contains 46 chromosomes arranged in 23 pairs, with one set inherited from each parent. These chromosomes house…

Introduction Mendelian inheritance, also known as classical genetics, is the foundation of understanding how traits are transmitted from one generation to the next. It is named after Gregor Johann Mendel, an Austrian monk and scientist who conducted pioneering experiments with pea plants in the mid-19th century. Mendel’s work revealed that inheritance follows specific patterns determined…

Introduction Genes are the fundamental units of heredity, serving as the blueprints for life. They are segments of DNA (deoxyribonucleic acid) that encode instructions to build proteins, which perform the majority of functions in living organisms. Genes influence not only physical traits, such as eye color or height, but also play a crucial role in…

DNA, or deoxyribonucleic acid, is the fundamental molecule that carries the genetic instructions essential for the growth, development, functioning, and reproduction of all living organisms. It serves as the blueprint for life, determining the traits inherited from one generation to the next. DNA is organized into genes and chromosomes within the cell nucleus in eukaryotic…

Genetics is the branch of biology that studies genes, heredity, and the variation of organisms. It explains how traits are transmitted from parents to offspring and how genetic information contained in DNA determines the development, functioning, and characteristics of living organisms. Genetics is fundamental to understanding evolution, human health, agriculture, and biotechnology. By studying genetics,…
