Mice have two forms of the gene for hair texture. Straight hair (H) is dominant to curly hair(h). They also have two forms of the gene that determines the length of their tails. Short tails(T) are dominant to long tails(t). What would be the phenotypic ratio of the offspring if a mouse that was heterozygous for straight hair and had a long tail was crossed with a mouse that had curly hair and was heterozygous for tail length.

The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-saharan africa than among those of african descent living in the united states. even though this gene causes sickle-cell disease, it also provides some protection from malaria, a serious disease that is widespread in sub-saharan africa but absent in the united states. discuss an evolutionary process that could account for the different percentages of the sickle-cell gene among residents of the two regions.
