Attached earlobes (see image on the right below) is a recessive condition in humans. Unattached earlobes (seen on the left) is the dominant form of the trait and it displays complete dominance. Two parents who are heterozygous for this gene mate. What phenotypic ratio do you expect in their offspring? To earn full credit, write the genotypes of the parents below, make a Punnett square using the table feature in Canvas (click on the Insert menu above and then scroll down to Table and then select the correct size to include the gametes and offspring in the table), and write the phenotypic ratio and the phenotypes for all genotypes expected.
