Question

d. Edward VII of England is the son of Queen Victoria. The modern English monarchy is descended from Edward. According to the pedigree, Edward VII is unaffected even though his mother is a carrier. Prince William is the great-great-great grandson of Edward VII. Is it possible for Prince William and Princess Catherine to have a child affected with hemophilia? Assume Princess Catherine is not affected. Explain your answer. Evolution Connection The human tongue can only detect four flavors. The front of this organ responds to sweet sensations, salt on the front sides, sour on the sides of the mid-region, and bitter on the back. It is peculiar that we detect bitter tastes just before we swallow. Develop a hypothesis that explains why the "bitter meter" is on the back of the tongue rather than the front of this organ. To help answer the question you should know that many plant toxins are bitter tasting.

Answer 1

D.since haemophilia is the x-linked revessive disease,and queen is carrier ,hence only one allele is affected .

Hence Edward is unaffected have x chromosome to be normal .

Hence his offspring will be offered normal x chromosome always .

It depends upon the female partner wather the grandson is affected/normal.

Since Princess Catherine is normal ,she will always give normal allele.

HENCE HIS GRANDSON WILL BE NORMAL.
