Summary Introduction

To enlist:

The syndromes associated with abnormal sex chromosomes.

Introduction:

Humans contain 46 chromosome (2n) and are diploid in nature but at the time of fertilization only 23(n) chromosome is receive by mother and 23 (n) chromosome is receive by father to form a zygote by the process of meiosis. Zygote is formed by the transfer of male gamete (sperm) and female gamete (ova). Zygote receives 46 chromosomes.

Sometimes due to nondisjunction of chromosome during meiosis the chromosome number fails to separate and abnormal chromosome are fused to form an abnormal zygote Such abnormal chromosome number causes some syndromes like Down syndrome, Klinefelter syndrome, Turner syndrome, Triple X syndrome are associated with sex chromosome.

*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
