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.
In species with environmental sex determination,
a. sex is determined during development as an embryo.
b. environmental conditions determine the sex of an individual.
c. hermaphroditism always occurs.
d. Both a and b are correct.

Materotrophyarrow_forwardIs this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c. In sexual reproduction, the offspring have the same combinations of genes as their parents. d. Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phasearrow_forwardHow would self-sacrifice of male redback spiders be an adaptive behaviour? 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. Males are able to mate with one female, then mate with another female nearby, before being devoured by the first female. C. Males only use self-sacrificing behaviour once they have mated with several females and have exhausted their sperm supplies. d. The chance of a male meeting more than one female is quite low; self-sacrifice maximizes mating time with and sperm transfer to any female the male finds.arrow_forward
