hello jai hind bachhon.... in this video we discussed about Pedigree analysis| Genetic disorder✓ #cbse12thbiology #biology #upboard Pedigree analysis is a genetic tool used to study the inheritance of traits and genetic disorders within families across multiple generations. It involves creating a pedigree chart, a family tree diagram with standardized symbols: squares for males, circles for females, shaded shapes for individuals expressing a trait or disorder, and unshaded for unaffected ones. This visual representation helps track how traits are passed down, revealing patterns of inheritance such as autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive.Genetic disorders are often analyzed through pedigree charts to understand risks and inheritance mechanisms. Autosomal dominant disorders, like Huntington's disease, require only one copy of a mutant allele and typically appear in every generation, affecting both sexes equally. Autosomal recessive disorders, such as cystic fibrosis or Tay-Sachs disease, need two copies of the mutant allele and often skip generations since carriers (heterozygous individuals) do not show symptoms. X-linked disorders, often recessive, are more common in males because males have only one X chromosome, while females can be carriers without symptoms.Pedigree analysis is crucial for genetic counseling, allowing prediction of disease risk in offspring and helping families understand their genetic history. It also aids researchers in identifying inheritance patterns and supports medical diagnosis. Despite challenges like incomplete penetrance or complex traits, pedigree analysis remains a foundational method for studying inherited human diseases and traits. pedigree analysis and genetic disorders, pedigree analysis genetics, pedigree analysis and, pedigree analysis neet, pedigree analysis, pedigree analysis tricks, pedigree analysis amoeba sisters, #pedigree #details of #pedigree analysis, pedigree analysis autosomal dominant, pedigree analysis class 12
