Breeding of Animals

CLONINGIn 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

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.

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.

Selective breeding

- is a process where we choose

the characteristics we want in an animal.

Asexual Reproduction

Regeneration

There are many animals that can regenerate complex body parts with full function and form after amputation or injury.

Budding- is a type of asexual

reproduction. It is most commonly associated with

bacteria and yeast, but some animal species reproduce

via budding, too.

Sexual Reproduction

External fertilizationusually 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.

Internal fertilization -is the union of an egg cell with a

sperm during sexual reproduction inside the body of a

parent.
