On the main page of blast, click on the link "list all genomic databases." how many genomes are currently available for making comparisons using blast? how does this limitation impact the proper analysis of the gene data used in this lab?

In laboratory investigation, BLAST is used to examine in contrast different genes, the information or result is used to develop a cladogram. A cladogram is treelike, with the terminal points of each branch standing for a certain species.

How many genomes are currently available for making comparisons using BLAST?

A total of 1500 genomes are currently available for making comparisons using BLAST

How does this limitation impact the proper analysis of the gene data used in this lab?

This limitation impact the proper analysis of the gene data used in the lab to give or supply a full whole or complete list of all likely genetic ancestors and/or relatives.
