One of the most variable Y chromosome STR systems (Y-STRs) is DYS385a,b loci, which exist in two polymorphic ... Between-population distances (in the form of FST or RST values) were illustrated ...

Save guides, add subjects and pick up where you left off with your BBC account. This is the line \(\text{x = 3}\): Similarly, lines in the form \(\text{y = b}\) will always be horizontal lines.

The general equation appears as \(Ax + By + C = 0\). However to build up an equation use \(y - b = m(x - a)\) where \(m\) is the gradient and \((a,b)\) is a point on the line.
