In a pea plants, green pod colour is dominant over yellow pods. 1000 seeds taken from a pea plant on germination produces 760 green pod and 240 yellow pod plants. The parental genotype and phenotype of the seed plant are 

(1) Heterozygous and yellow

(2) heterozygous and green

(3) homozygous and yellow

(4) homozygous and green

(2) Since the ratio is 3 : 1, it is evident that parent plant is heterozygous dominant (green).
