Balto's DNA: Unleashing Genetic Secrets

Introduction

Ever wondered how a legendary sled dog from 1925 could teach us about genetics? Smithsonian Magazine dives into the DNA of Balto, the heroic canine who braved Alaskan blizzards to deliver lifesaving serum. Scientists compared his genes to modern dogs and wild canines, revealing his exceptional genetic health and diversity. This study not only celebrates Balto's legacy but also opens new doors to understanding mammalian genetics. Get ready to be amazed by what a dog's DNA can tell us about evolution and health!

Phenotype vs. Genotype

Phenotype is all the visible traits (like height and hair color), while genotype is the set of genes that determine those traits. It's the difference between what you see in the mirror and the genetic instructions that got you there.
