Chapter 11 - Complex Inheritance and Human Heredity

This is an individual who is heterozygous for a recessive disorder:

• Inheritance

• Pedigree

• Carrier

• Genetic

Cystic fibrosis is caused by what?

• The gene that codes for a membrane protein is defective.

• Genes do not produce normal amounts of the pigment melanin.

• Absence of the gene that codes for the enzyme that breaks down galactose.

• Absence of a necessary enzyme that breaks down fatty substances.

A diagram that displays family relationships indicating traits or disorders.

• Punnett square

• Pedigree

• Monohybrid cross

• Chromosome map

This pattern of inheritance was observed by Gregor Mendel where one allele coding for a gene is deemed dominant and manifests in the phenotype over the other allele deemed recessive. 

• Codominance
• Complete Dominance 
• Multiple Alleles
• Epistasis

A person with blood type AB expresses two markers on the surface of their blood cells. Each marker is coded for by a different allele. 

• Complete dominance
• Multiple Alleles
• Codominance 
• Polygenic Inheritance
