Reproduction
↳
the of produce generation of
ability organisms to a new themselves .
↳
for survival and evolution ,
as an individual passes on its
genes to the next generation .
Types of reproduction :
asexual production of a generation by
•
new one parent
-
↳
binary fission (organism duplicates genetic material,
budding ( new organism develops from bud due
to cell division, vegetative reproduction ( part of a plant develops into a new one )
sexual production of a new generation by bringing the genetic material of two parents
together
•
-
both of reproduction produce the same kind of organism (to prevent out ) and
types species from dying
-
result in food being produced

Advantages of a sexual reproduction
↳ all individuals
can produce offspring therefore there's no expenditure of energy to make gametes Hind mate
↳
simple fast process only ,
involves mitosis .
↳ useful in stable conditions
↳
favourable mutation can spread rapidly enabling the population to adapt
quickly to new environmental
conditions ( resistance to antibiotics and insecticides )
Disadvantages of a sexual reproduction
↳
no variation in
offspring ( unless mutation ) as there is no recombination of alleles If the environment

results in variation which :
