T.H. Morgan:
Correct answer: D. Drosophila
- A. 1 chromosome pair
- B. Nucleotide
- C. F. Miescher
- D. Drosophila
Explanation
Drosophila, particularly Drosophila melanogaster, is closely associated with T.H. Morgan. He used fruit flies extensively in his genetic research and is renowned for his work on heredity and chromosomes using this model organism. Morgan's discoveries with Drosophila, such as the identification of sex-linked inheritance and the concept of gene mapping, laid the foundation for modern genetics. His studies with fruit flies led to significant advancements in our understanding of genetics and earned him the Nobel Prize in Physiology or Medicine in 1933.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
