8. CLONING
In reproductive cloning, researchers
remove a mature somatic cell, such as a
skin cell, from an animal that they wish to
copy. They then transfer the DNA of the
donor animal's somatic cell into an egg
cell, or oocyte, that has had its own DNA-
containing nucleus removed
9. Artificial insemination (AI)
- is the process of collecting sperm
cells from a male animal and manually
depositing them into the
reproductive tract of a female. One
can cite a number of potential
benefits from the use of artificial
insemination.
10. Embryo transfer
- refers to a step in the process of
assisted reproduction in
which embryos are placed into the
uterus of a female with the intent to
establish a pregnancy.
16. Budding
- is a type of asexual reproduction.
It is most commonly associated with
bacteria and yeast, but
some animal species reproduce
via budding, too.
18. External fertilization
usually occurs in aquatic environments
where both eggs and sperm are
released into the water. After the
sperm reaches the
egg, fertilization can then take place.
19. Internal fertilization
-is the union of an egg cell with a
sperm during sexual reproduction
inside the body of a parent.
