Question
A family of white tigers is depicted in the following pedigree. In answering the following questions, assume that white is determined by allelic differences at a single gene and that the trait is fully penetrant. Base your answers only on information in the pedigree. If a is true, b is false and c-e are true, enter TFTTT.
For the following questions, assume that white tigers are indicated by the unshaded symbols. White coat color could be caused by:
a Y-linked allele.
b. a dominant X-linked allele.
c. a dominant autosomal allele.
d. a recessive X-linked allele.
e. a recessive autosomal allele.

d. a recessive X-linked allele.
e. a recessive autosomal allele.
Explanation / Answer
Pedigree is not given but the answers are assumed
1) FTFFF
This is because, the If the allele on X chromosome determines the white color then it can be passed to offspring, since coat color is maternally inherited.
2) this answer would also be same as above FTFFF.
