Question

Meiosis of megaspore mother cell generally produces

• A. Linear tetrad
• B. Tetrahedral tetrad
• C. Decussate tetrad
• D. Isobilateral tetrad

Answer 1

The correct option is A Linear tetrad

Megaspore mother cell undergoes meiosis to form four haploid megaspores. The megaspore mother cell first divides to form a dyad which then finally forms a linear tetrad as a transverse wall is laid down after first meiotic division and similarly, second transverse division occur in the two dyad cells resulting in a linear tetrad. Tetrahedral, decussate and isobilateral tetrads are produced during microsporogenesis i.e. these are microspore tetrads. Hence, meiosis of megaspore mother cell produces a linear tetrad.

So, the correct answer is A.
