[Genetic-linkage] problem wtith mlink

[ohouyem from gmail.com]

Hi professionals!

I have a problem with mlink. I want to evaluate the risk of a fetus to
be affected. I have his genotype with three markers flanking the
morbid gene. The disease is autosomal recessive, with incomplete
penetrance.

I used mlink for this purpose, but I have this error message:
“Fatal error detected in procedure inputdata
Error detected reading pedigree record  1. Illegal code for sex 17”

I indicate the sex of the fetus, and the affected allele as
undetermined. Bur I have the same error message.


Please please , I’m waiting for your help
Thank you
