Suppose you do a cross between two parents who are both heterozygous for two traits, such as flower color ( red or white, red is dominant) and petal shape ( narrow or wide, narrow is dominant). If there are 160 offspring, how many would you expect to have red flowers with narrow petals?

Solution
Answer:
A heterozygous parents for two traits will yield:
9 (homozygous dominant):3 (heterozygous):3 (heterozygous):1 (homozygous recessive)
Meaning 9 out of 16 will be red flowers with narrow petals
Of the 160 offsprings= 90 will be red flowers with narrow petals
