Genes, although tiny and imperceptible, play a pivotal role in shaping our physical characteristics, unless modified by medical intervention. Originating from the first man and woman, genes come in various types, with Y-Chromosomes and mtDNA being extensively studied by geneticists. Y-DNA is inherited exclusively from fathers to sons, perpetuating through generations of male lineage, while mtDNA is passed from mothers to all their offspring, albeit only daughters can transmit it further.
