what are splice junction mutations?
Answer / swapna
G-to-C substitution at the 5 end of an intron in the muscle-
specific subunit gene.
The mutation destroys the high-consensus GT sequence at the
5 splice junction of the intron, which causes skipping of
the preceding exon.
This is the second molecular genetic defect identified in
the myopathic variant of PhK deficiency.

The ABO blood system has been employed to settle cases of disputed paternity. Suppose, as an expert in genetics, you are called to testify in a case where the mother is type A, the child is type O and the alleged father is type B. How would you respond to the following statements of the attornies: a. "Since the mother has type A, the type O of the child must have come from the father and since my client is type B, he obviously could not have fatered the child." Made by the attorney of the alleged father. b. "Further tests revealed that this man is heterozygous and therefore he must be the father." Made by the mother's attorney.
In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?
In a cross AABBCC and aabbcc (P generation), what would be the frequency of AAbbCc in the F2 (assuming no linkage)?
