A mutagen is an agent that causes a mutation.

Adenosine deaminase deficiency and cystic fibrosis have been successfully cured with gene therapy.

Explain the difference between a genetic disease and a genetic predisposition.

The q-arm is the long segment of the chromosome.

Down syndrome results from nondisjunction of the twenty-first chromosome.

The p-arm and q-arm are determined by the location of the centromere.

A gene can be reduced to a sequence of DNA nucleotides.

If both parents have sickle cell trait,none of their offspring can have sickle cell anemia.

A recessive trait on an autosome will be expressed only if both chromosomes have a recessive gene.

A Punnett square can be used to determine the probability of two carriers of albinism having an albino offspring.

A karyotype can be used to detect Down syndrome.

Another term for a chromatin strand is a gene.

If one parent has sickle cell anemia and the other parent has normal blood,none of their offspring can have sickle cell anemia.

The study of the proteins that are made by the human genome is called proteomics.
