Rights Act of 18663 and then in section 1 of the Fourteenth. Amendment.4 In doing so, Congress set aside the Dred Scott hold-. ing, and restored the traditional precepts of citizenship by birth.5. Based on the first sentence of section 1,6 the Court has held.
Grouped into 23 pairs, we get one set from our mother and the other from our father. One of these pairs of chromosomes determines if a person is male or female: Males (XY) get the X chromosome from the mother and the Y chromosome from the father. Females (XX) inherit one X chromosome from each parent. The Fragile X premutation can be passed silently down through generations in a family before a child is affected by the syndrome.
When a mother is a carrier of an X-linked mutation, each daughter they have has a one in two (50%) chance of becoming a carrier and each son they have has a one in two (50%) chance of inheriting the condition.-linked inheritance. Some conditions are caused by a mutation on the X chromosome (one of the sex chromosomes). These are usually inherited in a recessive pattern â albeit in a slightly different way to the autosomal recessive pattern described above.
