Genetics is the study of genes, heredity, and variation in living organisms. It plays a crucial role in understanding how traits are passed down from one generation to the next.
One of the key concepts in genetics is the idea of dominant and recessive genes. Dominant genes are those that are expressed in an individual, while recessive genes are only expressed when paired with another recessive gene.
Genetic research has led to many breakthroughs in medicine, including the development of gene therapies for various diseases. It has also provided insights into human evolution and the relationships between different species.
Overall, genetics is a fascinating and complex field that continues to hold great promise for the future of science and medicine.
