Genotypes & Phenotypes
Genotypes and phenotypes are fundamental concepts in the field of genetics, offering insight into the genetic makeup and observable traits of organisms. While genotypes refer to the genetic composition of an individual, encompassing the alleles inherited from both parents, phenotypes represent the observable characteristics resulting from the interaction between genotype and environment. Understanding the relationship between genotypes and phenotypes is essential for unraveling the mechanisms of inheritance, genetic variation, and evolutionary processes. This introductory paragraph provides a concise overview of these key concepts, setting the stage for a deeper exploration of their significance in genetics.
