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.
The genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.
<h3>What is a dominant genotype?</h3>
A dominant genotype is a set of gene variants characterized to have dominant alleles that mask the expression of recessive alleles in heterozygous individuals in cases of complete dominance.
In conclusion, the genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.
