8. Pedigree 4812 also segregated a lethal pale green which lived as long as any albino or yellow seedling would. It starts as a normal appearing green plant and then gradually becomes more and more yellow. There is also a bright green segregant in the pedigree. Progenies in which both pale green and bright green coexist give the ratio 9 blue green ‑ 3 bright green : 4 pale green (or yellow). Some progenies are homozygous blue green, some homozygous bright green. Since pale green is lethal, it is impossible to produce homozygous pale green progenies.
