In Snapdragon F1 progeny shows pink coloured flowers when a cross in made between red flowered and white flowered plants.
What is the genetic reason of this phenomenon?

In Snapdragon F1 progeny shows pink coloured flowers when a cross in made between red flowered and white flowered plants. Find out the phenotypic ratio of F2 generation of the same cross.

The 1 : 2 : 1 ratio with the pink flower In the F_1 -generation indicate the phenomenon of

Transfer of pollen grains from the anther to the stigma of a flower is called pollination. Grass plants generally have small , inconspicuous flowers while plants belonging to many angiosperm bear conspicuous coloured flowers. What are the salient features present in these two groups for effective pollination?

Nicotiana sylvestris flowers only during long days and N.tobacum flowers only during short days. If raised in the laboratory under different photoperiods. they can be induced to flower at the same time and can be cross fenjlized to produce self-fertile offspring. What is the best reason for considering N. sylvestfis and N. tobocum to be separate species?

In an experiment. Red flowered 4 O'clock plant is crossed with a While flower. 4 O'clock plant. The F1 generation plant is crossed and prcduced the F2 generation. The phenotypic and genotypic ratio is 1:2:1. Name the type of inheritance? Explain.
