Question

Red flowered snapdragons are crossed with white flowered, producing all pink snapdragons in the F1. What would you expect if you crossed red with red?

options: all pink , 3/4 red and 1/4 white, all red , 1/2 red and 1/2 white

Answer 1

Answer:

All red .

Hope this is right.......

Answer 2

If we crossed red flowered snapdragons with each other, we would get all red flowers.

This is an example of incomplete dominance.

In this case, a red flower has the genotype RR, a white flower has the genotype rr whereas a pink flower has the genotype Rr[ any heterozygous flower is pink].

So now we cross two red flowers:

RR × RR

This gives us the resultant genotype as RR which shows that all the flowers produced are red.
