What is a karyogram?

What is whole genome sequencing?

Whole genome sequences determines the order of the bases in an organism's genome, allowing for the comparing of genomes across species

What is the current use of genome sequencing?

to compare genomes and further understand evolutionary relationships between species

What is a future use of genome sequencing?
