Simple Mendelian and Codominance

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance
• Mendelian Inheritance
• Homozygous Inheritance

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

• Incomplete Dominance
• Co dominance
• Independent assortment
• Recessive inheritance

A plant shows incomplete dominance in size. A tall plant (TT) is crossed with a medium plant (TS). What fraction of plants will also be tall?

• 100 %
• 75%
• 50%
• 25%
