What are the 2 types of variation?

1. interspecific=variation that exists between species 2. intraspecific=differences within a species

1 of 5

Exaplain the causes of intraspecific vairation and give an each of each

enviromental factors-effects phenotype (apperance) e.g amount of minerals in soil (plant) and genetic factors-inherited, alleles make up genotype=variation in phenotype e.g blood type

2 of 5

Defintion of an alleles

Different versions of the SAME gene

3 of 5

Why is random sampling used?

represent whole population, to eliminate bias

4 of 5

What is the normla distribution? and give a definiton for standard diviation

1. bell-shaped graph due to values on both sides of the mean, 2. spread of values around the mean
