Summary Introduction

To predict:

The results that the researchers would have found when they conducted their genetic study of Solomon Islanders.

Introduction:

5%to10% of Solomon Islanders had blonde hair and there were many hypotheses to justify this. It was earlier believed that early European explorers had left back their blonde hair trait in the Solomon Islanders.

Expert Solution & Answer
Check Mark

Explanation of Solution

Geneticists did not agree with the belief that European explorers were the reason for blonde hair. They believed that TYPR1 (tyrosine related protein 1) gene and malfunctioning of melanin protein is responsible for the same. If blonde hair were due to European explorers, then the researchers would have heterozygous population having recessive genes for black hair. These heterozygous populations will produce recessive blonde hair gene.

Conclusion

The researchers would have found recessive black hair gene in heterozygous population.

Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?
