A person is heterozygous for the Freckles phenotype (Ff) and also heterozygous for the PTC-tasting phenotype (Tt).
This person's genotype for these two traits is represented as FfTt.
A) How many unique gametes could be produced by this individual if you consider these two traits?
B) List the different allele combinations that could result.
if your phenotype is for a dominant trait, such as curly hair, then your genotype is?
a: also for curly hairb: for both curly and straight hair c: a complex combination of all hair typesd: unknown, the alleles could be heterozygous or homozygous
