Question

Which of the following is NOT a reason why Drosophila melanogaster was chosen for Morgan's linkage experiments?

Options

• It has only 4 pairs of chromosomes

• It has a short life cycle of approximately 2 weeks

• It has multiple pairs of chromosomes for complex analysis

• It produces large numbers of offspring

Answer 1

Drosophila was chosen specifically because it has only 4 pairs of chromosomes, making it easier to study—not because it has multiple pairs. The limited chromosome number, short generation time, numerous offspring, and easily observable traits made it ideal for genetic research.
