What is the purpose of CODIS?

Back

CODIS (Combined DNA Index System) is a database that stores DNA profiles for use in criminal investigations.

What are alleles?

Back

Alternate forms of a trait; the different possibilities for a gene.

What does homozygous mean?

Back

When a child inherits the same allele from both parents.

Front

What does heterozygous mean?

Back

When a child inherits different alleles from each parent.

Front

What is the role of SNPs in genetics?

Back

Single Nucleotide Polymorphisms are variations at a single position in DNA among individuals.

Front

What is a locus?

Back

The specific location of a gene or DNA sequence on a chromosome.
