Final answer:
α-thalassemia with a cis deletion is more prevalent in Asian populations.
Step-by-step explanation:

Various forms of thalassemia are more common in different populations. In the case of α-thalassemia with a cis deletion, it is more prevalent in Asian populations. This may be due to genetic factors specific to those populations.
