Answer 1

Molecular Genetics is the specialty of medical genetics that is about 25 years old and began with the ability to test DNA markers linked to disease genes.

Step-by-step explanation:

The specialty of medical genetics that is about 25 years old and began with the ability to test DNA markers linked to disease genes is Molecular Genetics.

Molecular genetics is a field of study that focuses on the structure and function of genes at the molecular level. It involves techniques such as DNA sequencing, PCR, and genetic mapping to analyze DNA and identify disease-causing genes. Through molecular genetics, scientists have made significant advancements in understanding genetic diseases and developing genetic tests.
