Define reproduction
Production of a new generation of organisms from an existing generation
Define strategies
Genetically determined behaviour
What is the reproductive effort?
To produce the maximum number of surviving offspring while using the least amount of energy
What is courtship?
Behaviour and signals designed to attract another animal for mating and breeding
What are the two different forms of courtship?
• Simple strategies • Complex strategies
What are simple strategies?
Makes use of chemical, visual and auditory stimuli
What is complex strategies?
More elaborate and unique to the species
What type of men do females favour?
• larger • more elaborate features • more energy and courtship 
How does courtship maximise?
• ensure they find suitable mates • sexual behaviour is timed • energy expenditure by the male • lead to a strong healthy offspring
Define fertilisation
Joining of the nucleus of the sperm and egg
What are the two types of fertilisation?
• external • Internal
Why is external fertilisation not an ideal process?
• wasteful • fertilisation is not certain
How can we maximise reproduction during external fertilisation?
• huge number of eggs and sperm • courtship rituals
What are the two types of internal fertilisation?
• cloaca • penis
How does internal fertilisation maximise reproduction?
• more certain • fewer damage needed – energy is saved
Define ovipary, ovovipary, vivipary
The moment at which the future offspring separated from a parent
ovipary, ovovipary, vivipary indicate
• where the embryo developed • how the embryo and fetus were nourished
Where does ovipary occur?
Eggs develop outside of the parents. It was fertilise internally or externally. The egg yolk is that’s only food
What fluids occur when the sperm is travelling from the penis?
Seminole fluid (male) and mucus membrane fluid (female)
How is internal reproduction maximise?
• fewer gummy are needed which saves energy • more certain because the Gaby 😉💙’s are as close as possible
Where does fertilisation occur in ovovipary?
Internally and it is kept inside the female until it hatches
What is the food for ovovipary?
Yolk
How is the animal dependent on the mother in ovovipary?
Physical protection and gaseous exchange
How does ovovipary maximise reproduction?
• fewer eggs are produced • your embryo is less vulnerable to production and cold temperatures • born fully developed
