WebFeb 9, 2024 · Using tetrad dissection, a non-parental ditype (NPD) tetrad that contains two Ura+ and two Ura− spores can be isolated, which will occur on average in 1/6 tetrads for unlinked genes . Even if the double mutant is inviable, Mendelian genetics indicates that the presence of two Ura− spores means the remaining two spores in that tetrad must ...
