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.
No, the vast majority of DNA mutations are not physically noticeable, and those that are noticeable physically are mainly cosmetic differences, such as a change in hair color, or heterochromia.
