I'm trying to make a pedigree of the present lines of our Zebrafish Facility to avoid the endogamy with a visual reference.

We have all data of parent-descendent for each line ID, date of birth, etc...

I tried using the R Package Kinship2, but the function pedigree assumes I have different individuals with Male or female sex. And don't let me work with ZF lines, because for each line I have both males and females (and duplicating data for each line will be pointless).

I accept any suggestion about the package, or if I can use another program.
