Interpret your graph by (a) explaining in words any pattern indicating a possible relationship between the variables and (b) hypothesizing the possible cause of such a relationship.

A graph is a diagrammatical representation of point, line segments, curves, and areas that show a variable's relationship with other variables. It includes vertices and edges. Examples of graphs are bar graphs and pie charts.

The graph shows a positively correlated relationship between genetic distance and reproduction isolation. This is because, with the increase in distance between two populations, reproduction isolation value is also increasing.

Here, the reproduction isolation value changes with the distance between two populations. It also shows that the reproduction value is increased with the increase in the distance between two populations.

A hypothesis can be made that the individuals of different populations with a particular distance cannot contact each other and so cannot mate and gene flow blocks between them.
