Genetic Disorders: Chromosomal Aberrations

This lecture covers the genetic basis of sex determination, inheritance of genes on sex chromosomes, and chromosomal aberrations leading to genetic diseases. Topics include deletions, duplications, inversions, translocations, and their impact on gene expression. The lecture also discusses non-disjunction during meiosis, resulting in conditions like Turner syndrome and aneuploidies. Furthermore, it explores genomic imprinting, the role of epigenetics in gene expression, and the consequences of chromosomal rearrangements. Key concepts include understanding gene linkage, dosage compensation in the X-Y system, and the six basic inheritance models in humans.
