Question

What was the phenotype of all F1 hybrids produced in Morgan's Drosophila experiment?

Options

• Black body and vestigial wings, resembling the female parent

• A mixture of both parental phenotypes in equal proportions

• New recombinant phenotypes with grey body and vestigial wings

• Grey body and long wings, resembling the male parent

Answer 1

All F1 hybrids in Morgan's experiment resemble the male parent with the phenotype of grey body and long wings because the male parent contributed the dominant alleles (BV).
