|
Sexual Reproduction
|
|
|
No donation of genetic material. All offspring are identical to the parent.
|
Asexual Reproduction
|
|
|
Asexual patterns include
|
Budding, dividing in two, reversion to sexual reproduction
|
|
|
Forms of sexual reproduction
|
Seperate male and female organs (Dioecious in plants), Hermaphroditic (organism that possess both sexes), Monoecious (possess seperate sexes on one plant)
|
|
|

|
Simutaneous and sequential.
|
|
|
The male organ of one individual is mated with the female organ of the other and vice versa.
|
Simultaneous hermaphrodite.
|
|
|
Organisms that are males at one part of their life cycle and females in another part
|
Sequential hermaphrodite.
|
|
|
What are the different mating strategies (systems)?
|
Monogamy and Promisquity.
|
|
|
The formation of a lasting pair bond between one male and one female.
|
Monogamy.
|

|
|
|
The time and energy allocated to reproduction is known as?
|
Reproductive effort.
|
|
|
Mode of reproduction where an organism sacrifices future prospects by expending all its energy in one suicidal act of reproduction.
|
Semelparity (female puts much energy and resources into offspring).
|
|
|
Organisms that produce fewer young at one time and repeat reproduction throughout their lifetime are called?
|
Iteroparous (female puts little energy into reproduction).
|
|
|
Condition where the young are born or hatched in a helpless condition and require considerable prenatal care.
