Free ear lobes (F) are dominant over attached ear lobes (f). What will be the phenotypic and genotypic ratio of the offspring from a cross between two heterozygous free ear lobed parents?
a. Phenotypic ratio: 3 attached ear lobes to 1 free ear lobe; Genotypic ratio: 1 FF to 2 Ff to 1 ff
b. Phenotypic ratio: 3 free ear lobes to 1 attached ear lobe; Genotypic ratio: 1 Ff to 2 FF to 1 ff
c. Phenotypic ratio: 1 attached ear lobe to 3 free ear lobes; Genotypic ratio: 2 Ff to 1 FF to 1 ff
d. Phenotypic ratio: 1 free ear lobe to 1 attached ear lobe; Genotypic ratio: 1 FF to 2 Ff to 1 ff
