Every individual possesses two alleles for a trait, but only one is passed on to a gamete (sperm or egg).
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 Principles of Genetics
While Mendel identified the patterns, it wasn't until the 20th century that scientists identified as the physical carrier of this information. DNA is organized into structures called chromosomes . A gene is a specific segment of DNA that contains the instructions for building proteins—the workhorses of the body. Every individual possesses two alleles for a trait,
Genes for different traits are inherited independently of one another. A gene is a specific segment of DNA
Understanding the principles of genetics allows us to grasp the continuity of life. From Mendel’s simple pea plants to the complexity of the human genome, genetics reveals the intricate code that connects all living things and provides the tools to shape the future of biology and medicine.
The "Central Dogma" of molecular biology describes the flow of this information: DNA is transcribed into RNA, which is then translated into proteins. This process determines an organism's (observable traits) based on its genotype (genetic makeup). Genetic Variation and Mutation
