Genotype and Phenotype

Have you ever wondered why siblings can look so different, even though they share the same parents? The answer lies in the genotype and phenotype.

The genotype is a unique combination of alleles inherited from your parents.

For instance, your genotype includes alleles for traits like eye color, hair type, or height.

In contrast, the phenotype represents an organism's observable characteristics, which result from the interaction of its genotype with environmental factors.

For example, human height is influenced by several genes, not just one. The combination of alleles found in these genes helps determine height.

However, diet and exercise influence how these genes are expressed, affecting the phenotype. So, even if two individuals have the same set of genes for height, their actual heights may not be the same.

This understanding is key in genetics, agriculture, and medicine, as it explains how traits are inherited through the genotype and expressed as the phenotype.
