Question

which of the following animals is a genetic male? multiple choice bird - zw grasshopper - xo drosophila - xxy honeybee - diploid

Explanation:

• Birds use ZW sex determination: ZW = female, ZZ = male. So Bird-ZW is female.
• Grasshoppers use XO sex determination: XO = male, XX = female. So Grasshopper-XO is male.
• Drosophila uses X:A ratio: XXY (2 X, 2 sets of autosomes) → X:A=1 → female.
• Honeybees: haploid = male (drone), diploid = female (worker/queen). So diploid honeybee is female.

Answer:

Grasshopper - XO
