genetic loci

Genetic loci are specific, fixed positions on a chromosome where particular genes or genetic markers are located. Think of a chromosome as a long book, and loci as the exact pages or paragraphs where important information (genes) can be found. Each locus represents a unique address on the chromosome, helping scientists identify where genes influencing traits, health, or ancestry are situated. Variations at these locations can lead to differences in characteristics or susceptibility to certain conditions. Understanding loci is essential for studying genetics, inheritance, and how traits are passed through generations.
