At present, scientists can determine the arrangement or relative positions of genes or DNA sequences on a chromosome. How does this knowledge benefit us?

Explanation

The knowledge of the arrangement or relative positions of genes or DNA sequences on a chromosome indeed has several benefits. It allows us to understand the pedigree of livestock (Statement 1) as it helps in tracing the genetic traits and lineage of animals.

It also aids in developing disease-resistant animal breeds (Statement 3) by identifying and manipulating specific genes responsible for disease resistance.

However, it is not accurate to say that it enables us to understand the causes of all human diseases (Statement 2).
