Genetic models

For diallelic loci, fit genetic models (multiplicative, dominance, recessive) to one or more case/control and/or TDT samples. 

# case/control samples :      Equal allele frequencies? : 
# TDT samples          :     Multiplicative model only? : 
Disease prevalence     :
Enter sample details below, C/C samples first (see below for guidance):
All numbers must be whitespace-delimited. All genotype counts must be greater than zero for non-multiplicative models.

For case/control data, enter the six counts:
    Case   Control
AA  n1     n2
Aa  n3     n4
aa  n5     n6
For TDT data, enter the seven offspring counts given specific parental mating type: 
AA offspring | AA x Aa parents
Aa offspring | AA x Aa parents

AA offspring | Aa x Aa parents
Aa offspring | Aa x Aa parents
aa offspring | Aa x Aa parents

Aa offspring | aa x Aa parents
aa offspring | aa x Aa parents
For example, for one case/control and one TDT sample:
30 13
67 56
32 48

23 18
45 76 34
35 28
