Missense mutation- this point mutation causes a change in the DNA, if the base substitution results in an amino acid substitution in the synthesized protein, i.e. sickle cell anemia
Nonsense Mutation- a base substitution resulting in a nonsense codon.
The tendency of close -together genes to segregate together
* Genes that are located quite close to each other almost always segregate together, and so are * inherited together.
( a cross over event is unlikely the closer two genes are to each other on a chromosome)
