<) Any ALL green pod parent is either homozygous GG, OR
<heterozygous Gy,
<Gb, Gw, or Gr. In addition, 2) Any ALL yellow pollen parent is
<either homozygous YY, OR heterozygous Yg, Yb, Yw, or Yr.
It is much simpler: green is always gg and yellow leaf is Yg
<3) The coloration in this pod parent (and extrapolated, possibly all
<Hostas) is controlled by one set of genes at one specific locus,
<not multiple genes at multiple loci.
THis in this context, only is true for yellow leaves
4) The pollen parent does not bring any chloroplast DNA to the
party, so f there are any change in the color of the leaf of the
resultant F1 progeny these are due to DNA changes in the nucleus
as a result of thecross.
Correct?
YES
THE HYPOTHESIS ( NO, THE Conclusion based on the results of
experiments:
1) If you cross a yellow (in appearance) pollen parent with a green
(in appearance) pod parent, and you get 50% of the progeny to
exhibit the color of the pollen parent, then ANY and ALL yellow
progeny are due to a dominant nuclear DNA trait in the pollen
parent. -
YES CORRECT-----------------------------
