*Sickle cell disease is a constitutional corpuscular hemolytic anemia related to an abnormal structure of the globin chain. It is an autosomal recessive disease, which means homozygosity is necessary to fully express the illness.
*It corresponds to the synthesis of an abnormal hemoglobin, HbS, which is different from normal Hb (HbA).
*The S allele (located in the chromosome 11), responsible for the anomaly, is especially widespread in the African continent, it is also found in other regions of the Mediterranean.

*Mutation GAG to GTG leading to the substitution Glutamine by a valine in position 6 of the chain of the globine.</span>
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
- The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
- The genotype of a tree that is heterozygous for both trait would be BbTt
- Thus, the cross would be bbTT x BbTt

Answer:
2c. Jamestown Settlement and the "Starving Time"
Explanation:
The first joint-stock company to launch a lasting venture to the New World was the VIRGINIA COMPANY OF LONDON. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.
In 1607, 144 English men and boys established the JAMESTOWN colony, named after King James I.
The colonists were told that if they did not generate any wealth, financial support for their efforts would end. Many of the men spent their days vainly searching for gold.
As a consequence, the colonists spent little time farming. Food supplies dwindled. MALARIA and the harsh winter besieged the colonists, as well. After the first year, only 38 of the original 144 had survived.
