Hi all, 2 questions on the above. 1) Could someone give me a comprehensive definition of the term 'segregating population' please? As I understand it, it is a population of one particular species that is the progeny of a cross, ie Mendels pea example would have a segregating population being the progeny of Aa and Rr. Is that right? 2) Is it only a segregating population that be used for molecular markers? Many many thanks. Phil
