Kids DNA Book
あらすじ・解説
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.
The classification of Y-DNA and mtDNA into letters helps delineate the genetic relationships across different populations and regions. However, these genetic markers often exhibit a mosaic distribution due to intermarriages, conflicts, and migrations throughout history. Despite these diversifications, humanity remains fundamentally linked to its ancestral roots, with distant connections to the original progenitors persisting through millennia of genetic mingling. Thus, while genetic variations have enriched our species over time, our collective genetic heritage underscores the profound interconnectedness among human populations worldwide.
