QUESTION 1

In this monohybrid cross, the allele for purple flowers (P) is dominant over the allele for
white flowers (p). A cross is carried out between a purple homozygous flower (PP)
and a white homozygous flower (pp).

Parental Generation (P₁)

 Purple homozygote: PP
 White homozygote: pp

F₁ Generation

All offspring inherit one dominant allele from the purple parent and one recessive allele
from the white parent.

 PP × pp → All offspring are Pp

All F₁ individuals are heterozygous purple flowers.

F₂ Generation

The F₁ generation is self-crossed:

 Pp × Pp

Punnett Square
P p

P PP Pp
