A testcross is a cross of an individual drake to a drake known to be homozygous for the recessive allele of a gene or genes under study. Testcrosses are used to determine the genotype of a drake displaying the phenotype associated with the dominant allele of one or more genes. Testcrosses are also used to determine whether two genes are sorting independently, and if they are not, testcrosses allow the measurement of the map distance between genes.

The genetic code allows the instructions for synthesizing proteins using a set of twenty amino acids to be encoded in nucleic acids. Each of the 64 possible three-base codons has a specific meaning. It is often useful to refer to the genetic code when studying sequence variation among alleles of a gene.

DracoBase was built using a number of publicly-available bioinformatics resources. These may be of use to developers.
