Every individual possesses two alleles for a trait, but only one is passed on to a gamete (sperm or egg).

Genetics is not just about stability; it is also about change. occurs through recombination during reproduction and through mutations —random changes in the DNA sequence. While some mutations are harmful, others provide the raw material for evolution, allowing species to adapt to changing environments over generations. Modern Applications and Ethics Principles of Genetics

Some alleles are dominant and will mask the expression of recessive alleles. The Role of DNA and Chromosomes Every individual possesses two alleles for a trait,

Today, the principles of genetics have expanded into genomics, allowing us to sequence entire genomes. This has revolutionized medicine through personalized treatments and gene editing technologies like CRISPR. However, these advancements bring significant ethical questions regarding privacy, "designer babies," and the potential for unintended ecological consequences. Conclusion While some mutations are harmful, others provide the

An essay on the principles of genetics explores the fundamental rules governing how traits are passed from parents to offspring. At its core, this field explains the biological "blueprint" that defines every living organism. The Mendelian Foundation
