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.
