A tall plant (TT) is crossed with a short plant (SS) and a medium plant (TS) results. This is what type of inheritance pattern?

• Incomplete Dominance
• Codominance

How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

• There is no difference
• The heterozygous genotype has a unique phenotype
• There is no heterozygous genotype
• There is only one phenotype regardless of genotype.

Which type of inheritance causes both traits to be expressed equally in the heterozygote?

• Complete Dominance
• Incomplete Dominance
• Co-Dominance
• Sex-linked
