The chromosomal basis of linkage was worked out mainly through breeding experiments on Drosophila by
Correct answer: D. Thomas Hunt Morgan
- A. Gregor Mendel
- B. Jean Baptiste Lamarck
- C. James Watson
- D. Thomas Hunt Morgan
Explanation
Morgan showed that certain Drosophila characters were inherited together and tied to the sex chromosomes, founding chromosome mapping. Mendel worked before chromosomes were understood, and Watson's fame rests on the structure of DNA.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
