Three crosses were carried out in pea plants with respect to flower colour violet/white (V/v) and flower position axial/terminal (A/a). Study in the table the crosses 'a', 'b' and 'c' where parental phenotypes and their $\displaystyle \mathrm{F}_{1}$ progeny phenotypes are given.

Parental plants (Phenotypes)	$\displaystyle \mathrm{F}_{1}$ Progeny (Phenotypes)
(a) Violet, axial × white, axial	$\displaystyle 6$/$\displaystyle 16$ white, axial $\displaystyle 2$/$\displaystyle 16$ white, terminal $\displaystyle 6$/$\displaystyle 16$ violet, axial $\displaystyle 2$/$\displaystyle 16$ violet, axial
(b) Violet, axial × white, terminal	$\displaystyle 1$/$\displaystyle 4$ violet, axial $\displaystyle 1$/$\displaystyle 4$ violet, terminal $\displaystyle 1$/$\displaystyle 4$ white, axial $\displaystyle 1$/$\displaystyle 4$ white, terminal
(c) Violet, axial × violet, axial	$\displaystyle 3$/$\displaystyle 4$ violet, axial $\displaystyle 1$/$\displaystyle 4$ white, axial

Find the genotypes of each of the parental pairs of crosses 'a', 'b' and 'c'.
