Fig. 9. Reduced centrioles in unc mutant spermatocytes. Transverse and
longitudinal sections of centrioles in (A) wild-type (y w) and (B)
mutant (y w unc) spermatocytes show similar ultrastructure with
microtubule triplets, but both the proximal and distal sections of mutant
centrioles are shorter. (C) Lengths of the proximal and distal parts of
longitudinally sectioned centrioles. Asterisks indicate the centrioles shown
in A and B.
