Oswald Avery is best known for his groundbreaking work in the 1940s that identified DNA as the substance responsible for heredity. In a series of experiments, he demonstrated that DNA extracted from virulent strains of bacteria could transform non-virulent strains into virulent ones, proving that DNA carries genetic information. This pivotal discovery laid the foundation for modern molecular genetics and helped establish DNA as the genetic material in living organisms. Avery's work significantly advanced the understanding of inheritance and the role of nucleic acids in Biology.

How is the equal genetic contribution of male and female parents ensured in the progeny?

The equal genetic contribution of male and female parents is ensured through the process of meiosis, where each parent's gametes (sperm and egg) only contribute half of their genetic material to the offspring. During fertilization, one sperm fuses with one egg, combining their genetic material to create a zygote with an equal genetic contribution from both parents.


What was the contribution of Oswald Avery to modern genetics?

Oswald Avery, an early molecular biologist and immunochemist, is best known for his discovery in 1944 (with his co-workers Colin MacLeod and Maclyn McCarty) that DNA is the material of which genes and chromosomes are made.
