Other Patterns of Inheritance

What is codominance?

• when an allele is not completely dominant over the other.

• both alleles are completely expressed.

• trait controlled by 2 or more genes.

• a gene that has more than 2 alleles.

What is incomplete dominance?

• when 1 allele is not completely dominant over the other.

• a situation which the phenotypes produced by both alleles are completely expressed.

• meiosis.

• mitosis.

Are the characteristics of any organism are only controlled by genes?

• yes.

• no.

• maybe so.

• I have no idea.
