Question
Chapter 51, Problem 3A
Summary Introduction
Introduction:
A biological system that “determines the development of sexual characteristics in organism” is known as sex determination. The offspring that are produced by the sexual reproduction have two sexes, but occasionally, in the place of one or both sexes there are hermaphrodites.

c.
Sexual reproduction is associated with an increase in homozygosity.
d.

Which of the following correctly describes hermaphroditism?
A.
It is an example of sexual reproduction because it involves a male and a female.
B.
It is an example of asexual reproduction because only one individual needs to be involved.
C.
It is an example of sexual reproduction because it involves fusion of two gametes.
D.
