Phenotypic Diagnosis

Identifying the cause of a disease based on observable characteristics, like symptoms or physical traits.

Genotypic Diagnosis

Analyzing genes to diagnose a disease, providing highly accurate results.

Disadvantage of Genotypic Diagnosis

Genotypic diagnosis can be expensive due to the complexity of the procedures and analysis.

Focus of the Module

This module tackles both the fundamental principles of genetics and their application in molecular diagnosis.

Study Notes

Methods of Diagnosis

  • Molecular diagnosis uses characteristics to determine the cause of disease.

Genotypic Diagnosis

  • The greatest advantage of genotypic diagnosis is that it allows for precise identification of genetic mutations.
  • The disadvantage of genotypic diagnosis is that it can be complex and time-consuming.

Module Overview

  • The main focus of this module is on the relationship between genetics and disease.

DNA and Proteins

  • DNA contains the instructions for making proteins, which perform various functions in the body.

Genetics History

  • Gregor Mendel is known as the Father of Genetics.
  • Gregor Mendel discovered the laws of inheritance through his pea plant observations.

Human Chromosomes

  • Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
  • Sex chromosomes (X and Y) are responsible for determining the sex of an individual.

Genetics Fundamentals

  • A gene is a unit of heredity that carries information from one generation to the next.
