Answer:

Please see the answer below

Explanation:

a. The roman numerals represent the various generations in the pedigree.

    I represents first generation

   II represents the second generation

b. The half shaded square and circle representing the parents means that both of them are carriers for the trait in question. <u>Tay-Sachs disease is an autosomal recessive inheritance, assuming the trait is represented by the allele </u><u>a</u><u>, the gentoypes of the parents would be </u><u>Aa </u><u>and </u><u>Aa </u><u>respectively.</u>

c. Still on the assumption that the disease is represented by the allele a. If offpsring II4 which happens to be free of the Tay-Sachs allele marries a person that also does not carry the Tay-Sachs disease gene, the cross will be as shown below.

AA   x   AA = AA, AA, AA, and AA.

<em>All the children would be free from the Tay-Sach's allele. That is, they will be homozygous normal.</em>
