<u>reason;

Answer:
heterozygous purple pea plant and heterozygous purple pea plant
Explanation:
Suppose the gene controlling flower colour in pea is P. Allele P is dominant over allele p. So, PP and Pp produce purple flowers and pp produces white flowers. If two heterozygous purple pea plants (Pp) are crossed :
Pp X Pp :
P p
P PP Pp
p Pp pp
As evident, the progeny will have genotypic ratio of 1 : 2 : 1 ( PP : Pp : pp ) and phenotypic ratio of 3 : 1 ( Purple : white )
Hence two heterozygous purple pea plants will produce 3:1 ratio of purple to white pea plants.
