A number of different types of mutations in the HBB gene can cause human β-thalassemia, a disease characterized by various level
Lubov Fominskaja [6]

Answer:

Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.

Explanation:

Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.  

In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.

balu736 [363]
<span>"Genetic drift is more likely to have an impact on small populations."

Genetic drift is changing the frequency in the allelic pool of a population. This phenomenon impacts mainly smaller populations because these populations have only a few copies of the alleles present. If a change in the frequency of the alleles happens then it may cause the disappearance of certain alleles because there are only so many copies.</span>
