The main difference between Klinefelter and Turner Syndrome is that Klinefelter syndrome is a trisomy whereas Turner syndrome is a monosomy. We will then look at five syndromes that result from aneuploidy, including occurrence and characteristics of each syndrome. Klinefelter syndrome occurs when a boy is born with one or more extra X chromosomes. Individuals with this syndromes are phenotypically males but with tendency towards femaleness. Down syndrome Klinefelter syndrome Trisomy X Turner syndrome This study resource was shared via CourseHero.com Correct A triploid cell has three sets of chromosomes: the two from the diploid gamete and the one from the haploid gamete. On the contrary, the combination of DS and Turner syndrome is very rare (estimated frequency is 1 in 2,000,000) (3–7). Turner's syndrome. 00:06 These are genetic problems with the sex chromosomes. The Human Genome Project – humans have 30,000 genes. Turner syndrome is also known as monosomy of the X chromosome. Often, symptoms are subtle and subjects do not realize they are affected. In the case of Klinefelter syndrome, the male has 2 X chromosomes and 1 Y chromosome (Figure 1). Down syndrome, Turner syndrome, and Klinefelter syndrome constitute the most common chromosomal abnormalities encountered by primary care physicians. The presence of a Y chromosome is necessary for an individual to be male. I am one of them. C. Down Syndrome. Having extra X chromosomes can cause a male to have some physical traits unusual for males. It is congenital, which means it is present from birth.

Klinefelter syndrome is caused by the addition of an X chromosome. They are all aneuploidy conditions that result from nondisjunction during meiosis (gametogenesis- formation of gametes). Discuss, under the guide of genetic disorder, one of the following diseases: Down Syndrome, Klinefelter Syndrome, Turner Syndrome, Tay-Sachs Disease, Phenylketonuria, or Cystic Fibrosis Simultaneous coexistence of DS and Klinefelter syndrome is relatively frequent. As children, they often learn to speak much later than other children, and may have difficulty learning to read and write. D. Turner Syndrome.

Translocation type DS constitutes about 5% of all down syndromes but DS with translocation not including chromosome 21 is quite rare (1). • Down Syndrome Trisomy 21 (three) • Turner Syndrome (XO) • Klinefelter Syndrome (XXY) Polygenic inheritance In most cases, many genes interact to produce a particular characteristic. The typical features of Turner's syndrome include short stature, infertility, and hypogonadism. In particular, we will be investigating polyploidy and aneuploidy, two types of chromosomal variation. 00:12 These patients usually have male hypogonadism.
