In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?

Ultrastructural studies have led to the characterization of two distinctive cytological
pathways of PCD in plants;
I) Vacuolar-type PCD
II) Hypersensitive response-type (HR-type) PCD
a) cytosol and all its organelles, including the plasma membrane, are completely brokendown
b) The vacuole loses water, resulting in marked cell shrinkage, contraction from the cell wall,
and nuclear DNA degradation
c) PCD occurs in leaves in response to microbial attack
d) cell wall is either partially or completely digested as well, as in endosperm tissue
e) Continued water loss from the cytosol leads to the breakdown of the plasma membrane
and the release of residual cellular contents into the apoplast
Given characterization of PCD pathway match with its type PCD?
