Consider two pairs of alleles, G/g and H/h, that follow complete dominance inheritance. The initial cross consisted of GG hh males and gg HH females, and the F I female progeny were test crossed with gg hh males to produce 380 Gghh progeny out of 1000 total progeny. What is approximate distance between Gene G and H.
