What is a variation
Differences in organisms
How many types of variations are they and what are they
Continuous variation
Discontinuous variation
Genetic variation
Enviroment variation
What is continuous variation
A feature that changes gradually over a range of value e.g height or weight
What is a discontinuous variation
You fit into one group or another and the feature doesn’t change during your lifespan e.g. hair colour, eye colour, blood type
What is discontinuous variation controlled by
Controlled by genes only
What is continuous variation controlled by
Controlled by genes and environment
What is environment variation
The environment conditions that an organism lives and grows in causes differentiation between organisms
What is genetic variation
Are characteristics that are determined by the genes inherited from their parents
What is a advantage and disadvantage of asexual reproduction
Advantage- only one parent needed and all offspring’s are clones
Disadvantage- no variation between offspring
What is and advantage of sexual reproduction
Advantage- variation between offspring
Disadvantage- need two parents, mutations
What is sexual reproduction
Sexual reproduction is when two parents create offspring with a mix of their genes.
What is asexual offspring
Asexual reproduction creates offspring that are genetically identical to a single parent.
What is an advantage and disadvantage of sexual reproduction
What is asexual reproduction advantage and disadvatage
What is variations
Differences in organisms
What is continuous variation
A feature that changed gradually over a range of value
Give me an example of continuous variation
Height, weight
What is continuous variation controlled by
Genes and environment
Wha dis discontinuous variation
You got into one group or another and the feature doesn’t change during your lifespan
Give me and example of discontinuous variation
Hair colour, blood type, eye colour
What is discontinuous variation controlled by
Controlled by genes only
Define the term mutation
A random change in the sequence of DNA
Define survival of the fittest
Having an advantage over other organisms allowing you to survive
What is the scientist responsible for evaluation
Charles Darwin
