Question

Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?

1) 0%

2) 25%

3) 50%

4) 100%

Answer 1

Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?

RR x rr= Rr, Rr, Rr, and Rr

Red x White= Pink heterozygous

Rr x rr= Rr, Rr, rr, and rr

Pink x White= 0% as both Pink and white shares it with 2:2 or 50:50%
