Bioaccumulation
-
Bioaccumulation is a process of build up of chemicals in an organism that takes place if the rate of intake excesses the rate of excretion
If slugs eat lettuce that has pesticide and then a hedge hog eats the slug the hedgehog is affected by the pesticides so the hedgehog population decrees.By Bioaccumulation

This means that the Tertiary consumer will consume a large amount of the contaminant and this can cause them harm
Genetics
Everyone inherits half there chromosomes from there mother and half from the farther through sperm and egg combining (fertilization)
-
A gene codes for a characteristic eg. Hair colour. You could get one allele from your mother and one from your farther. Eg. Brown hair from one,red from the other
-
It is possible for you to be a carrier of a recessive characteristic. you won't appear to have it on the outside but offspring could inherit it from you.

Variation
-
-
Continuous Variation like height,hair colour etc.
