Two pink coloured flower on corssing resulted in 1 red,2 pink and 1 white flower progeny. The nature of the cross will be

A

double fertilisation

B

self pollination

C

cross ferstilisation

D

no fertilisation

Text Solution

Verified by Experts

The correct Answer is:
B
The nature of the cross will be cross fertilisation. Fertilising a plant using pollen from another plant of the same species is cross-fertilisation. Double fertilisation is a complex fertilisation mechanism of flowering plants. It involves fusion of a male and female gamete. Self-pollination is a form of pollination that occur in a flower that has both stamen and carpel.
