Hint: All scientist work was interrelated to each other's discoveries, most of them were cytologists and based their work on chromosomes. The discoveries were based on research on very small organisms that are related to humans in a laboratory. The basis of all the discoveries was based on Mendel’s discoveries.

Complete answer:
-The mechanism of sex willpower changed into usually a thriller, even though, Henking located 'X frame' in 1891. It became most effective inside the 20th century. X chromosome performed the main role in the sex willpower of bugs. They further observed that the intercourse determination in insects was of XO kind. Since the X-chromosome is concerned with the determination of sex, it came to be known as the sex chromosome.
-The Chromosomal Theory of Inheritance, the chromosomal idea of inheritance was given through Boveri and Sutton inside the early 1900s. It is the essential theory of genetics. According to this concept, genes are the devices of heredity and are determined within the chromosomes.
-Thomas Hunt Morgan became awarded the Nobel Prize in Physiology or Medicine in 1933. The paintings for which the prize turned into offered become completed over 17 months at Columbia University, starting in 1910 with his discovery of the white-eyed mutation inside the fruit fly, Drosophila
People with Sickle Cell Anaemia have Sickle haemoglobin (HbS) which is different from the everyday haemoglobin (HbA). When sickle haemoglobin offers up its oxygen to the tissues, it sticks collectively to shape long rods within the purple blood cells making those cells rigid and sickle-formed.
-Alfred Henry Sturtevant (November 21, 1891 – April five, 1970) was an American geneticist. Sturtevant constructed the primary genetic map of a chromosome in 1911. Throughout his career, he labored on the organism Drosophila melanogaster with Thomas Hunt Morgan.
-The Boveri–Sutton chromosome principle (also known as the chromosome idea of inheritance or the Sutton–Boveri principle) is an essential unifying theory of genetics which identifies chromosomes
The correct answer is option (I), i.e., A, B, C, D, and E

Note: To differentiate among the discoveries always plan to learn from the beginning of the particular topic discoveries started and then to the latest one, for example, discoveries were mainly started from Mendel experiment, then comes chromosomal inheritance then the gene locations and so after many with their respective decades.
