Jr College
Where does breeding fit in life?
w First,
animals meet basic survival needs
w Reproduction
is next on the list, assures immortality of its genetic material
w Thus,
must meet basic needs of animal first
Vertebrate Reproduction Overview
What is studied?
w Sperm
/ egg production:
Reproductive organs
Hormonal control / cycles
Secondary sex organs
w Fertilization:
Sperm / egg characteristics
Medium
Fertilization process
Genetics
What is studied? (contd)
w Embryo
development:
Cell division
Differentiation
Placentation
(mammals)
w Hatching
/ birth:
Shell / amnion
characteristics
Triggers to hatching
Triggers to parturition
What is studied? (contd)
w Offspring
development:
Cell division and
specialization
Lactation (mammals)
Sexual maturation and mating
w Normal
reproduction vs. problems with the system
w Modification
of reproduction
Why study animal reproduction?
w Complete
understanding of animals under your care
w Understand
physiology to sustain captive population
w Control
repro processes:
Increase reproductive
potential
Control genetic traits
How do we investigate animal reproduction?
w Utilize
the scientific method of investigation in research!!
Scientific Method
