A scientific discovery that was made many years ago is what we call the theory of applied genetics. Genetics is the study of patterns of inheritance of specific traits. Throughout history, many new discoveries on the theme of genetics were founded. The basic units of applied genetics were discovered in the late 1800s. Discovering the characteristics of applied genetics helps us understand the means of sexual reproduction and asexual reproduction. Genetics is the key to life, and from the many discoveries we have came upon, we now know what happened for us to get here, and how we are who we are in the world today. .
Since the late 1800s, we began to make discoveries of life and how traits in cells are passed on. Beginning in 1865, Gregor Mendel researched factors that we have not founded yet and discovered the visible traits of cellular organisms and reproduction. In 1875, Charles Darwin proposed that gemmules are an important factor of inheritance. In 1882, Walther Flemming discovered chromosomes and mitosis. By the early 1900s, the discoveries of actual genes, the pairing up of chromosomes, and how chromosomes were carriers of heredity were made. Also, a discovery was made that the X and the Y chromosomes determine the gender of a fetus. These are just the basic building blocks of the fundamentals of early applied genetics. Just from the information provided above, we can ensure that by a male and a female reproducing, we know that the child of the species will inherit traits from both of their parents. To determine the gender of a child, we know that there are both X and Y chromosomes distributed within the male and female sex cells to tell us what the child will be. By this point in time, we still are not able to determine the specific factors of these discoveries like what the genetic pair of the X and the Y chromosome determines and how it is determined. We just simply know that there is an X and a Y chromosome to determine the gender of an offspring.
