n1m |
The number of males with allele 1. |
n0m |
The number of males with allele 2. |
n2f |
The number of females with genotype (1, 1). |
n1f |
The number of females with genotype (1, 2). |
n0f |
The number of females with genotype (2, 2). |
nm |
The number of all the males to be analyzed. |
nf |
The number of all the females to be analyzed. |
rho |
