1
Q
Allelic Heterogeneity
A
Different types of mutations in the same gene/locus
Which result in the same phenotype?
2
Q
Locus Heterogeneity
A
Mutation at one or different locus/loci
Which result in similar phenotype
3
Q
Complete Penetrance
A
A mutant dominant gene is capable of causing abnormal phenotypic manifestations
4
Q
Reduced (Incomplete) Penetrance
A
A mutant dominant gene is incapable of causing abnormal phenotypic manifestations
5
Q
Pleiotropy
A
Phenotypes affect more than 3 systems
6
Q
Variable expression
A
1 genotype, different phenotypes
Same genetic disease, but with different phenotypic results
