-epistasis 
-linkage 
What is pleiotropy? 
Ans: When 1 gene (locus) has more than 1 effect on an individuals phenotype 
(eg. W allele in cats causes both white fur and deafness) 
What is epistasis? 
Ans: a gene at one locus alters the phenotypic expression of a gene at a second locus 
(eg. W allele masks all other colour or pattern genes in cat coat when present) 
P 
Ans: frequency of the homo dominant (AA) genotype
