The genotype of a pea plant producing violet flower is denoted by VV and that of a pea plant producing white flower is denoted by vv.
When these two are crossed :
What colour of the flower would you expect in the F1 progeny ?

Give the percentage of violet flower plant produced, if F1 plants are self-pollinated

In what ratio would you find the genotype of VV and Vv in the F2 progeny ?

Solution

Dear Student,

1. The colour of the flower that is expected in the F1 progeny after the cross between plants bearing violet flowers (VV) and the plant bearing white flower (vv) is Vv(violet).

2. When F1 plants are self pollinated, the percentage of plant bearing violet flower would be 75%.

3. The ratio can be obtained by carrying out the selfing of the F1 generation.

â™‚ /â™€ V v

V VV Vv

v Vv vv

As can be seen from the cross VV:Vv ratio is 1:2.

In the pea plant, purple colour of flower is dominant over white colour. Progeny obtained by crossing pure purple flowered plants with white flowered plants are self-pollinated. The resulting plants produced are:
