Answer:
Sickle cell disease is due to a type of substitution mutation.
Explanation:
Sickle cell disease is a condition that is transmitted from parents to children in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
The mutation that occurs in sickle cell disease is due to an alteration in the β-chain of hemoglobin, caused by the substitution of thymine base by adenine in the DNA that determines it. As a result, valine replaces glutamic acid in the β-chain amino acid sequence, with the consequences described.
- <em>The other options are not correct because </em><u><em>deletion, duplication and translocation </em></u><em>correspond to chromosomal mutations, not responsible for sickle cell disease.</em>
The similarities in the structure of the three species is due to their sharing a common ancestor while the differences is due to adaptation.
<h3>What is divergent evolution?</h3>
Divergent evolution is evolution where individuals who shared a common ancient ancestor process to have differing structures due to differences in their habitats.
All three species that Flor observed having similar structures is because they had a common ancestor.
The species had differences because they evolved to adapt to their different environments.
Wall geckos and Pacific gulls have temporal holes in their skulls as adaptations to their habitat.

Occurs between prophase 1 and metaphase 1 of meiosis.
It is natural selection. Try to remember from those three selections that natural is where the animal does it by itself. The other two are where humans interfere with it.
