Final answer:
The specific base pair sequences for genes like the Sex-determining Region Y (SRY) gene can be obtained from the GenBank database, maintained by NCBI.
Step-by-step explanation:
The specific base pair sequences for genes like the Sex-determining Region Y (SRY) gene can be obtained from the GenBank database, which is maintained by the U.S. National Center for Biotechnology Information (NCBI) and is available online free of charge. GenBank is a widely used genetic sequence database where researchers deposit genetic information for public use. It contains the sequence data of anonymous donors and allows the comparison of newly discovered or unknown sample sequences with the existing data.
