Genotype-Phenotype Map

The genotype-phenotype map describes how an organism's genetic makeup (genotype) influences its physical traits (phenotype). Genes, which are segments of DNA, carry instructions for building and maintaining the body. However, the relationship isn't always direct; a single gene can affect multiple traits, and environmental factors can also influence how genes express themselves. Think of the genotype as a blueprint, and the phenotype as the finished building. This map helps scientists understand how genetic variations lead to differences in appearance, health, and other traits among individuals.
