Non Mendelian Genetics- Incomplete Dominance & Codominance

Non Mendelian Genetics

Learning Objectives

SW learn the different types of Non- mendelian genetics: Incomplete Dominance, Codominance

Multiple Choice

A genotype where only recessive alleles

were passed on from both parents for one trait

bb aa tt ll

• Heredity

• Homozygous Dominant

• Homozygous Recessive

• Phenotype

Multiple Choice

A genotype where only dominant alleles were passed on

from both parents for one trait

BB AA TT LL

• Homozygous Recessive

• Homozygous Dominant

• Dihybrid

• Heredity

Multiple Choice

The letter symbols for both homologous alleles.

BB Bb bb AA Aa aa

• Genotype

• Phenotype

• Recessive

• Dominant

Multiple Choice

The instructions of this allele are covered up by the other allele in a homologous pair. Symbolized by a small letter.

• Homozygous

• Dominant

• Recessive

• Genetics

Multiple Choice

The instruction of one allele covers up the instruction

of the other allele in a homologous pair. Symbolized by a capital letter.

• Recessive Allele

• Dominant Allele

• Heredity

• Trait

Multiple Choice
