Consider the following information for a dihybrid cross. The dominant allele F codes for freckles, whereas the recessive allele f codes for no freckles. The dominant allele E codes for long eyelashes, whereas the recessive allele e codes for short eyelashes. Both parents have the genotypes of ee and Ff.
Indicate the following:
(1 ) the phenotype of both parents,
(2 ) the possible gametes that each parent can make,
(3 ) all of the possible phenotypes for the offspring, and (4 ) the phenotypic ratio obtained after the Punnett square is drawn.
(1 ) Both parents have the phenotype of freckles and short eyelashes. (2 ) The gametes each parent could make are Fe and fe. (3 ) All possible phenotypes for these traits would be as follows (in correct order): freckles and long eyelashes, freckles and short eyelashes, no freckles and long eyelashes, and no freckles and long eyelashes. (4 ) The phenotypic ratio is 0:12:0:4.
