Question

Thomas Hunt Morgan conducted his experiments on linkage using which organism?

Options

• Drosophila melanogaster (fruit fly)

• Pisum sativum (garden pea)

• Arabidopsis thaliana (thale cress)

• Mus musculus (laboratory mouse)

Answer 1

Morgan used Drosophila melanogaster because it had only 4 pairs of chromosomes, a short life cycle of approximately 2 weeks, produced large numbers of offspring for statistical reliability, and displayed easily observable traits such as eye color and wing shape.
