GENETICS PROBLEM SOLVING
Monohybrid Crosses
Free ear lobes in humans is dominant (F) to attached earlobes (f). Show the cross between two individuals that are heterozygous for free earlobes. Solve by filling out a Punnett square. What will be the probable genotypic and phenotypic ratios of their offspring?
