Summary Introduction

To determine:

The consequences that might have happened to the color-blind allele in Pingelapese population after the typhoon if Mwanenised had had no children or only five children.

Introduction:

Inbreeding is a phenomenon, in which mating is performed between closely related individuals (such as cousins). Inbreeding causes homozygosity and there are several diseases in humans that are linked with homozygous recessive alleles. Thus, inbreeding increases the chances of such diseases.

Expert Solution & Answer

Explanation of Solution

When typhoon occurred in Pingelap Island, only twenty people were able to survive that typhoon. So, inbreeding was the only option for them. Mwanenised was one of the male survivors of the typhoon. He was the heterozygote carrier of the color blind allele (achromatopsia disease). He had ten children, 50% of the children were normal and 50% were the carriers. As inbreeding occurred, achromatopsia became common among people.

Mwanenised was responsible for spreading the genes of the disease on island. If he had had no children, the disease would not have spread across the Island. If Mwanenised had only five children, the incidence of disease would be lesser than previous and lesser individuals would have had the disease.

Conclusion

Inbreeding should be avoided as it results in homozygosity of alleles that can cause several diseases in humans.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
