Answer:
In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.
In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.
A translocation that moves a gene from an area of euchromatin to heterochromatin would typically cause a(n) reduction in the expression of the gene.
<h3>What is euchromatin?</h3>
- A kind of chromatin that is sparsely packed, enriched in genes, and frequently engaged in transcription is called euchromatin.
- Contrasting with heterochromatin, which is compact and less accessible for transcription, is euchromatin.
- The human genome has 92% euchromatic DNA.
<h3>What is heterochromatin?</h3>
- Heterochromatin, often known as condensed DNA or densely packed DNA, has many different types.
- Between constitutive heterochromatin and facultative heterochromatin, these variations fall on a spectrum. Both contribute to how genes are expressed.
- Eukaryotic genomes contain heterochromatin, which serves a variety of purposes including regulating gene expression and preventing DNA replication and repair.
