Y chromosome

Klinefelter Syndrome Every year, approximately 3000 babies in America are born with Klinefelter Syndrome. Klinefelter syndrome, a genetic disorder known as XXY, is the most common sex chromosome disorder. Klinefelter occurs when the presence of at least one extra X chromosome is in each of the cells. Because chromosomes, contains all the genes and DNA, are building blocks of humans bodies, they are extremely crucial in determining the structure and traits of each individuals. Besides the physical changes

Turner Syndrome is a sex chromosome disease caused by complete or partial monosomy which effects on average 1 in 2500 females (Porth, 2005). Doctor Henry Turner, an endocrinologist, discovered Turner Syndrome in 1938 (Hayden, 2013). This disease is believed to be responsible for up to 10% of spontaneous miscarriages, and many Turner Syndrome pregnancies are electively aborted (Hayden, 2013). Turner Syndrome only affects females; however, this disease can affect all ethnicities. Patients who have

Those affected are born with an extra X chromosome (Belts & Frey, 2006). In 1942, Dr. Harry Klinefelter released a study concerning nine men who had little to no facial hair, enlarged breasts, small testicles, and were unable to produce sperm. The name of this syndrome originated from Dr. Klinefelter's name (Kenny & Henderson, 2015). This disease is often abbreviated as KS or referred to as 47 XXY. It is referred to as 47 XXY because of the extra chromosome in patients (Schoenstadt, 2016). Dr. Klinefelter

a sperm cell. And a person that has CES also has the chance of passing it on to their children although it is usually only passed down from carriers. As WebMD says, “Cat eye syndrome can't be cured because it's caused by a permanent change to a chromosome. But many of the symptoms can be treated.” (“What is Cat Eye Syndrome - Treatment” 2016). For some people who have minor symptoms, surgery will be an option. Anal atresia is fixed with surgery when a baby is born, heart defects and cleft lips also

Turner syndrome is a chromosomal condition that affects development in females. The most widely recognized element of Turner syndrome is short stature, which gets to be obvious by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is likewise extremely common. The ovaries grow ordinarily to begin with, however egg cells (oocytes) generally kick the bucket rashly and most ovarian tissue ruffians before birth. Numerous young ladies don't experience puberty

Tuners's syndrome is a disease affecting chromosomes of females where one of the two X chromosomes that a females contains becomes defective casing problems for the development of a female since conception. Thus, in a normal females there are 46 chromosomes in total, with the 45 chromosomes being autosomal(body chromosomes), while the 46th chromosome is the sex determining chromosome of a female XX or a make XY. However, Turner's syndrome does not affect males but rather females, which occurs

exactly what the turner syndrome is they just know that it has to do with a girls chromosomes. Most girls with turner syndrome are

Turner syndrome is a form of chromosomal condition that describes women and girls who have abnormal features, which are caused by either a partial or complete absence of the second sex, “X,” chromosome. Dr. Henry Turner was one of the first persons to describe these features in the 1938, and the syndrome is named after him. He observed and studied seven girls with similar “odd” features. “Turner Syndrome occurs in about one out of every two thousand females who are born, as well as in up to as many

evolutionary biologist J.B.S. Haldane. The rule states that in a species hybrid if only one gender is inviable or sterile, this is more likely to affect the heterogametic sex, which is the sex that has two different rather than two identical sex chromosomes. Haldane 's rule applies to the vast majority of heterogametic organisms observed. It includes when two species, where secondary contact in an area of sympatry results in incomplete reproductive isolation, form hybrids after allopatric speciation

an additional x chromosome in men, affecting their sexual development and leading to learning disabilities. Klinefelter syndrome is a genetic disorder caused by an extra X chromosome that leads to disabilities in men and has a complex cause. This syndrome is caused when a male has an additional X chromosome with the regular X and Y chromosomes. Klinefelter syndrome occurs by a process called nondisjunction. This condition occurs by a process called nondisjunction. When chromosomes are wrongly allocated
