14b. What is the genotype of the heterozygous parent?

14. Sc. What is the phenotype (albino or normal) of the homozygous recessive parent?

14. d. What is the phenotype of the heterozygous parent?

14. e. What percent of their offspring will be albino?

14. f. What percent of their offspring will be normal?
