dominant and recessive disorders

an organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease.

• carrier

• heredity

• phenotype

• purebred

The physical appearance of an organism based on traits

• Phenotype
• Meiosis
• Genetics

Alternative forms of a gene are called

Albinism 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 a necessary enzyme that breaks down fatty substances.

Galactosemia 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.
