QUESTION
Which one is the sperm defect in farm animals?
OPTIONS
(A) Dag defect
(B) Diadem defect
(C) Knobbed sperm
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
All three listed abnormalities are recognized sperm defects. The Dag defect involves severe tail and midpiece folding or coiling, the diadem defect involves characteristic nuclear vacuoles in the sperm head, and the knobbed sperm defect affects the acrosomal region. Since each named condition represents an abnormal sperm structure that can impair fertility, none of the individual choices alone includes the complete set.
