An organism's physical appearance is known as its
heredity
phenotype
genotype
pedigree
What does heterozygous mean?
the same allele for a trait has been inherited from both parents (TT or tt)
different alleles for a trait has been inherited from each parent (Tt)
When neither gene is fully dominant; offspring is a mixture of both
the different forms of a trait (hair color--> brown, blonde, red
