Question

what is the probability that you will get pink flowers when you cross two heterozygous flowers with incomplete dominance
50%
25%
100%
0%

Explanation:

Step1: Define alleles

Let's assume the alleles are R and r. Heterozygous flowers have genotype Rr.

Step2: Set up Punnett - square

When crossing Rr x Rr, the possible gametes from each parent are R and r. The Punnett - square has 4 possible combinations: RR, Rr, Rr, rr.

Step3: Determine phenotype in incomplete dominance

In incomplete dominance, RR might be red, rr might be white, and Rr is pink. Out of 4 combinations, 2 are Rr.

Step4: Calculate probability

The probability of getting Rr (pink flowers) is $\frac{2}{4}= 50\%$.

Answer:

50%
