What will you look for to identify the sex of the following? (a) Female Ascarissharply curved posterior end (b) Male frog a copulatory pad on the first digit of the hind limb (c) Female cockroachanal cerci (d) Male sharkclaspers borne on pelvic fins
Option D Tail end is straight in female Ascaris, while tail end is curved ventral words in male Ascaris. Anal cerci is present in both male and female cockroach, while anal style is present only in the male cockroach. The forelimbs in both frogs (male and female) bear small articular pads dorsally at the joints of digit, but the males possess a special nuptial, copulatory pad on ventral side of the first finger of each forelimb. Copulatory pad appears merely as rough patches, but during breeding season, these become thick and sticky. In copulation, the male strongly grips a female under her armpits by means of these pads. Claspers are modified inner edges of pelvic fins in male sharks.
