Question

In Drosophila, if $AAX$ ovum of the triploid female is fertilized by $AY$ spermatozoan, the resultant individual will be

• A. Male
• B. Intra sex
• C. Triploid male
• D. Metamale

Answer 1

The correct option is D Metamale

A metamale is a low viability Drosophila fruit fly with a male phenotype in which the ratio of X chromosomes to sets of autosomes is less than 0.5. For example: a fly with one X chromosome and two sets of autosomes is a normal male, a fly with one X chromosome and three sets of autosomes is a metamale.

So the correct option is 'metamale'.
