Yr 10 - Genetics and Evolution: Sexual & Asexual reproduction
Sexual reproduction
Requirements:
● Male gametes (sperm) and
female gametes (egg/ovum)
● Successful fertilization (sperm and egg fuse)
Result/outcome:
● Offspring that are genetically similar (but not identical) to parents + siblings
Asexual reproduction
This is done by many plants and occurs in some bacteria
Requirements:
● Female - 1 parent
● Ideal environmental conditions
*No sperm or egg involved
Result/outcome:
● Offspring that are genetically identical to the parent organism, as well as to
other offspring (siblings) ‘clones'
Sexual reproduction
Pros
Results in variation in a population
The population is more likely to survive any environmental changes/diseases
ConsVery energy + time expensive
Must find and court a mate, produce and combine gametes, incubate/grow offspring, look after offspring, etc.
Asexual reproduction
Pros
Really quick process, can grow populations
rapidly
Great for when environmental conditions are ideal
Cons
Results in no variation in the population
The population is unlikely to withstand
any environmental changes if they are
vulnerable to it
