Variation and Genetics is a key topic in FSC Biology and essential for MDCAT and entry test preparation. Genetics is the study of heredity and how traits are passed from one generation to the next through genes, which are segments of DNA located on chromosomes. Variation refers to the differences among individuals of a species, which can be genetic (inherited) or environmental (caused by surroundings). Understanding concepts like Mendelian inheritance, dominant and recessive traits, codominance, and mutations is crucial for explaining diversity, evolution, and adaptation. Mastery of variation and genetics is vital for FSC board exams and MDCAT entry test preparation, and PLS Academy provides concept-based lessons, diagrams, and exam-focused MCQs to help students excel in this topic.
