Answer:
Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.
Increasing understanding of genetics help in making new fields of health care, for example,
- Gene therapy helps in treating various genetic diseases such as cystic fibrosis et cetera.
- Molecular genetics help in the development of more precise methods for diagnosis such as ELISA.
- Pedigree analysis and karyotypes help in early detection of possible hereditary diseases.
- DNA fingerprinting helps in detecting criminal suspects, paternity test, identification of dead organism et cetera.

Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
