The axial filament of a mammalian sperm consists of
Options
A 9 double peripheral and 2 single central microtubules
Correct Answer
B 9 single peripheral and 2 double central microtubules
C 2 single peripheral and 9 double central microtubules
D 2 double peripheral and 9 single central microtubules
Correct Answer

Option A is the correct answer.

Detailed Explanation

The axial filament (axoneme) of a mammalian sperm, like all eukaryotic flagella and cilia, has the classic '9+2' microtubule arrangement: 9 peripheral doublet microtubules and 2 single central microtubules. This structure is highly conserved and is responsible for sperm motility.

Hint

Recall the characteristic microtubule arrangement of eukaryotic flagella and cilia.
