Summary Introduction
Introduction:
Male species of any organism is different from female specie of the other organism. It is due to the differences in their genes. Genes are the governing factor of each and every trait in all the organisms. There is a theory called the sexual selection. This theory is a type of natural selection and was proposed by Charles Darwin and Alfred Russell.

Students have asked these similar questions
A.
Water currents in the ocean are much stronger than any sperm. How do sperm and egg find each other?
B.
In humans there are no water currents and the volume of the female reproductive tract is relatively limited. Then, why does the male have so many sperm?
C.
Why do sea urchins have external fertilization?
D.
Then why don't the parents take care of the young?
E.
Because the urchin life involves two or more ecological niches, they are more susceptible to predation and exposure to environmental toxins. What environmental conditions, predators and toxins might they be exposed to at each stage?
Multiple choice (one answer is correct)
a. The food eaten by the female parent as a caterpillar determines the different caterpillar morphologies.
b.Temperature determines the different caterpillar morphologies.
c.Day length determines the different caterpillar morphologies.
d. Food type determines the different caterpillar morphologies.
Which of these situations offers the lowest “opportunity for selection” for males?
A. Females choose mates with a fancy ornament.
B. Every female chooses one male to mate with for life.
C. Locations that females need access to in order to reproduce are rare.
D. Males fight each other for access to groups of females.

Select one: a. When males meet a female and self-sacrifice, it activates enzymes that make his sperm more fit and able to fertilize more eggs. b.
