devlian [24]

Answer:

b. AMHT

Explanation:

The arrangement of genes on a chromosome can be estimated by considering the distance between the genes using the rate or frequency of their cross overs. Therefore, we have:

A-------------------18-------------------T

                        M---------9---------

--------------11-------------H

                          ---2---

Thus, using the arrangement above by selecting the letters as they occur, we have:

AMHT as the correct genes arrangement in the chromosome.
