Draw a Punnett Square representing the F₂ generation:

Solution

   Dominant Recessive

Purple (Pr) Red (pr)

Yellow (Y) White (y)

Coloured (R) Colourless (r)

1. Phenotypes of the parents:

Pr/Pr Y/Y r/r   X    Pr/Pr y/y R/R

purple, yellow, colourless X purple, white, coloured

F1 genotype : Pr Y r X Pr y R

F1 phenotype : purple yellow colourless X purple white coloured

F2 : ----------R ----------> Pr Y R (Purple, Yellow, Coloured)

--------- Y

----------- r -----------> Pr Y r (Purple yellow colourless)

Pr-------

----------R ----------> Pr y R (purple white coloured)

-------- y

----------- r -----------> Pr y r (purple white colourless)

2. Phenotypes of the parents:

Y/Y Pr/Pr R/R   x   Y/Y pr/pr r/r

yellow, purple, coloured X yellow, red, colourless

F1 genotype : Y Pr R X Y pr r

F1 phenotype : yellow, purple, coloured X yellow, red, colourless

F2 : ----------R ----------> Y Pr R (Yellow, Purple, Coloured)

-------- Pr

----------- r -----------> Y Pr  r ( yellow Purple colourless)

Y-------

----------R ---------->Y pr R (yellow red coloured)

-------- pr

--------- r -----------> Y pr r (yellow red colourless)

Apart from punnett square we can also know the F2 gametes by this above method. since I am not having a scaner right now to represent this problem through punnett square method, I am representing it like this. sorry for the inconvience if any.
