Question

When a pink flowered antirrhinum plant is test crossed,what is the phenotypic ratio?

Answer 1

Answer:

1:2:1. The inheritance of colour in a flower is an example of incomplete dominance.

When there is a cross between a true breeding white flower (rr) and true breeding red flower (RR), it produces a pink flower (Rr).

If the pink flower is selfed, the F2 generation creates plants that have red flowers and therefore pink flowers and white flowers are in the ratio of 1:2:1.

In it, both white and red flowers may not dominate each other. Both try to show their traits and therefore a median colour results.
