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.

In cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why?
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
