Understanding the genetic diversity within an organism is crucial in comprehending the complexities of heredity and evolution. One fascinating aspect of this diversity is the presence of two different alleles for a particular trait. This phenomenon, known as heterozygosity, plays a significant role in the expression of various traits and can have profound implications for the survival and adaptation of an organism in its environment. In this article, we will explore the concept of heterozygosity, its implications, and the fascinating organisms that exhibit this genetic trait.
