Samuel Gompers was the head of the largest labor federation of America known as American Federation of Labor. This organization comprised of workers that were skilled artisans, weavers, carpenters etc. He also headed the labor movement after actively forming a union of workers in the cigar industry. He himself was a cigar worker and thus could relate to the plight of the people working there. Young aged children were employed in cigar factories and the wage and benefits were not even enough to support survival of one.
Thus, Samuel arouses his voice to stand against the injustices done to the workers in cigar factory which later turned out to be mass movement.
Duchenne muyscular dystrophy is caused by a mutation on the X chromosome, so a male gets it from his mother's X, if she is a carrier. The male child gets a Y and no X from his father, so the disease is always transmitted through the X from the mother. If a female gets Duchenne muscular dystrophy she has to have two X chromosomes, one from a carrier mother and another from from an affected father. This is virtually impossible because most males die before childbearing age and there is no way a female child can get an X from a man who does not live long enough to procreate. About eight percent of carrier women do show some muscle weakness, but they do not have the disease.
