Role of Animal Reproduction

______________________________ is the process by which offspring are produced.

Offspring are of the same species and have traits of their parents.

Reproduction is essential if a species is to stay in existence.

______________________ reproduction involves the union of a male and a female gamete.

______________________ reproduction does not involve the gametes.

A _____________________ is a sex cell that can unite with other sex cells.
Reproductive Efficiency

What is reproductive efficiency and why is it important?
Sexual Reproduction

Two parents are required: male and female

The _________________ is the sex cell produced by male animals.

The _______________________ is the sex cell produced by female animals.
Male & Female Reproduction Systems 1

The union of sperm and egg is __________________________.

The fertilization of an egg to create a new life is ____________________________.
Breeding

________________________ is promoting animal reproduction so the desired offspring result.

Which system you use depends on many factors, such as:

_______________________ animal is one that is eligible for registry in a breed association.
o Parents must meet the requirements of that breed

__________________________ is mating animals of the same species but of a different breed.

When a non-purebred female animal, called a grade, is mated with a purebred male animal, the
process is called grading up.
The Value of Reproduction

Profit
o An animal that does not reproduce is of little economic value.

Livestock producers must produce a product that meets consumer demands.

Placing an emphasis on animal breeding can quickly increase the value of any operation.
Hormones

Male
o _______________________-critical for sperm development.

Female
o Estrogen______________________________________________________________________________

o Progesterone______________________________________________________________________________
