Converting an outcrossing F1 population for input into JoinMap

[Ira Herniter]

Hi, I am working with an interspecific F1 population in blueberry. Blueberry is an obligate outcrosser and highly heterozygous, meaning that my parents are highly heterozygous. When I use the "ABH Genotype" plugin, it removes nearly all of my markers because the parents aren't homozygous. 

However, I do need all of those data to include in the input file for JoinMap. Is there a way around the homozygous requirement in the plugin?

Thanks,

Ira
