Question
Chapter 46, Problem 10TYU
Summary Introduction
To determine: Why motile species are less often hermaphrodites.
Concept introduction:
Hermaphroditism is a condition in which an organism has both male and female reproductive systems. They produce both male and female gametes, so any two organisms can mate. In hermaphrodites, the gametes produced by meiosis have different genetic makeup than the parent organism.

The parasite's life cycle is as follows: Hermaphroditic adults live in the small intestine cavity of an infected human. The adult worm consists of rings that are produced in the anterior region of the worm, in which there is production of male gametes which fertilize female gametes then these rings (called proglottids) detach from the posterior end of the worm and exit in the external environment through the anus of the infected human. The eggs resulting from fertilization, present in the proglottids, are released and can infect a bovid if they are ingested along with grass. In the bovid, the developing eggs are particularly localized in the muscles of the bovid and turn into a shape called a cysticercus (each egg becomes a cysticercus). 1-Specify which species is the definitive host of the parasitic worm, justifying your answer 2- Specify the type of parasitism of this worm, justifying your answer 3-Specify which is (are) the…arrow_forwardThe following image is of a freshwater Hydra sp.
