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

• Incomplete Dominance

• Codominance

• Complete dominance

• Sex-Linked

Both traits expressed TOGETHER (not blended)

• Codominance

• Incomplete Dominance

• Mendelian trait

• Sex-linked

Many genes determine 1 trait (ex: skin color)

• Incomplete Dominance

• Polygenic

• Codominance

• Multiple alleles

For an XX female to express a recessive sex-linked trait, she must have....

• two recessive alleles
• a Y chromosome 
• one recessive allele
• two dominant alleles

Human height occurs in a continuous range because it is affected by the interaction of many genes, making it a(n)

• autosomal trait

• polygenic trait

• codominant trait

• sex-linked trait

Coat color in calico cats is an example of:

• Polygenic Traits

• Epistasis

• X-Chromosome Inactivation

• X-linked traits (same as sex-linked)

Which term is correctly matched with the description?

• Co-dominance occurs when two traits blend together to form a new phenotype.

• Human skin color is an example of codominant trait.

• Incomplete dominance occurs when traits blend producing a third phenotype.

• Human blood type is not an example of multiple alleles.

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.
