Arrange the ratios in the order of monohybrid test cross: incomplete dominance; and dihybrid cross.
Show Hint
In genetic crosses, remember that incomplete dominance shows a \( 1:2:1 \) ratio, complete dominance shows a \( 3:1 \) ratio, and a dihybrid cross results in a \( 9:3:3:1 \) ratio.
To arrange the ratios, we need to consider the phenotypic ratios for different types of crosses.
Step 1: Incomplete dominance
For incomplete dominance, the typical phenotypic ratio is \( 1:2:1 \) as seen in the ratio \( B \). This happens when the heterozygote phenotype is distinct from both homozygous phenotypes.
Step 2: Monohybrid cross
In a standard monohybrid cross with complete dominance, the phenotypic ratio is \( 3:1 \), which corresponds to \( A \).
Step 3: Dihybrid cross
In a dihybrid cross, where two genes are involved, the phenotypic ratio is \( 9:3:3:1 \), which corresponds to \( C \).
Thus, the correct order is:
\[
C - B - A
\]
