Answer: a line connecting her mother and father, a colored circle representing Jenna, and two empty circles representing her sisters

Explanation: Jenna's red hair can be determined by incomplete dominance.

Incomplete dominance is a condition where neither of the alleles responsible for a trait is dominant.

In incomplete dominance, one allele for a specific trait is not completely expressed over its paired allele. So, if an organism is heterozygous for a trait, it shows a third phenotype.
