What are the two types of reproduction? 
assexual reproduction
sexual reproduction
What is assexual reproduction?
Asexual reproduction is a type of reproduction involving only one parent, producing genetically identical offspring (clones).
What does assexual reproduction usually occur in? 
occurs in plants and unicellualr organisms.
clone
A clone is an organism or cell that is genetically identical to the parent organism or cell. A clone is a genetically identical copy of an organism or cell.
What are the advantages of asexual reproduction? 
fast and efficient reproduction
only one parent is needed (faster then sexual as one parent is needed)
can produce large numbers of offspring quickly
disadvantages of assexual reproduction
No genetic variation, leading to no variation in a population
disease may affect all the individuals in the population
The species may only be suited to one habitat.
assexual reproduction requires how many parents? 
1
Assexual reproduction produces what kind of organisms? 
clones
What is sexual reproduction? 
Sexual reproduction is the fusion of male and female gametes
sexual reproduction requires how many parents? 
2
What does sexual reproduction produce? 
variation in offsprings
gametes 
sex cells
fertilisation  
Fertilisation is the process where a male gamete fuses with a female gamete to from a zygote.
How many chromosomes are in a zygote? 
46
advanatges of sexual repriduction
produces variation in offspring
increases chances of survival in enviornment
disadvanatges of sexual reproduction 
Slower process than asexual reproduction.
Requires two parents, which may not always be available.
How many chromosomes are in a gamete? 
23
The term used to describe the number of chromosomes in an egg or sperm is _____. 
haploid
diploid 
A diploid cell is a cell that contains two sets of chromosomes, one set inherited from each parent.
What type of cell division produces gametes in sexual reproduction? 
meiosis
