Show Punnett squares for incomplete dominance in which a purple flower is crossed with a yellow flower, and all lavender flowers result. Draw Punnett squares that depict results of crosses between these lavender flowers. (F2 generation] and ratios, percentages, fractions, and decimals.

Solution

Purple flowers PP ; Yellow flowers pp

PP X pp In F1 generation all flowers are Pp , which is Lavender.

In F2 generation

Pp X Pp

P p

P PP Pp

p Pp pp

So in F2 generation purple flowers are 1/4 or 25 % or 0.25

Lavender flower 1/2 or 50 % or 0.5 ; yellow flower are 1/4 or 25 % or 0.25 of all progenies
