You are studying a plant that requires a period of cold treatment before it will flower. You subject a plant to cold treatment, return it to temperatures favorable for growth, and then compare the chromatin state of the DNA taken from: (1) meristem cells from a shoot that originated before the cold treatment; (2) meristem cells from a shoot that developed after the cold treatment;
(3) ovule egg cells from a flower on stem 1;
(4) seeds from a flower on stem 2.
You find that the chromatin states are the same within but differ between which two groups?

Question

The chromatin state is likely to be the same within the groups of meristem cells (1, 2) and reproductive cells (3, 4) but different between these two groups due to the cold treatment affecting flowering and subsequent reproductive development.
