Vedclass · Answer

(A) During fertilization,the sperm contributes its nucleus and the proximal centriole to the secondary oocyte. The proximal centriole is essential for the formation of the mitotic spindle apparatus,which is required for the first cleavage of the zygote. The distal centriole is generally involved in the formation of the sperm tail (axoneme) and does not play a role in the first cleavage.

Which centriole of spermatozoa is required for the first cleavage?
