Question

In the early 1900s, two scientists noted that there were many more genes than chromosome pairs, thus setting the stage for the suggestion that some gene loci might be linked during meiotic processes. Who were these two scientists?

Answer 1

Thomas Hunt Morgan and his colleagues were the early 1900s scientists who suggested that some gene loci might be linked on the same chromosome due to the observation of more genes than chromosome pairs.

Step-by-step explanation:

In the early 1900s, the scientists who noted that there were many more genes than chromosome pairs, thus setting the stage for the suggestion that some gene loci might be linked during meiotic processes, were Thomas Hunt Morgan and his colleagues. They provided the first experimental evidence to support the Chromosomal Theory of Inheritance, by meticulous microscopic observations and genetic crosses using the fruit fly, Drosophila melanogaster. Their research, culminating in the publication of 'The Mechanism of Mendelian Heredity' in 1915, played a crucial role in establishing chromosomes as the carriers of genetic material and demonstrating the phenomenon of genetic linkage and the existence of linked genes disrupting Mendel's predicted outcomes.
