If a hypothetical microspore mother cell is tetraploid. What will be the ploidy of the microspore?
The correct option is D Diploid
The microspore mother cell undergoes meiosis to produce microspores.
If the microspore mother cell is tetraploid (4n), then the microspore produced will have half the chromosome number.
Thus, the microspore will be diploid (2n).
