Chapter 51, Problem 4TY
Summary Introduction
Introduction: Fertilization is the process in which two different gametes, one male and other female, fuse together to produce an undifferentiated diploid cell called zygote. Fertilization can be of two types internal and external. The internal fertilization takes place inside the body of the female and the external fertilization takes place outside the body of the mother.

Internal and external fertilization differ in that species thata. produce an amniotic egg have internal fertilization.b. without an amniotic egg have external fertilization.c. produce live young have mammary glands.d. lay eggs are external fertilizers
If an egg cell were treated with EDTA, a chemical that bindscalcium and magnesium ions,(A) the acrosomal reaction would be blocked.(B) the fusion of sperm and egg nuclei would be blocked.(C) the fast block to polyspermy would not occur.(D) the fertilization envelope would not form.
Is 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 phase
