Y chromosome

syndrome affects males. It usually occurs during birth. Males usually live without knowing they have it. XYY syndrome is a disease that makes you very tall. XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.en.wikipedia.org/wiki/XYY_syndrome Xyy syndrome was discovered by a man named Sandberg in 1961.This disease…

3 Chromosomes are thread-like structures which consist of DNA and other proteins. Chromosomes are present in every cell of the human body so that information can be carried for that cell to develop. The human body normally consists of 46 chromosomes which then can be paired into 23 pairs. 22 pairs of chromosomes are similar in both males and females which are commonly known as autosomes. However, the 22nd chromosomes (X and Y) are different as these are the sex chromosomes. The human cell can…

caused when someone, usually male, has two X chromosomes and one Y chromosome giving them forty seven and not the normal forty six chromosomes. Males normally have an X chromosome and a Y chromosome and females normally have two X chromosomes. When either the sperm or the egg has a pair of sex chromosomes doesn’t succeed in separating formation, thus there is an extra chromosome causing the DNA abnormality during fertilization. This extra sex chromosome will copy its abnormal DNA into every cell…

Chromatin, chromatids, and chromosomes have different transformations in terms of mitosis and meiosis. Chromatin in Meiosis and Mitosis are shown differently in Interphase. In Mitosis, the chromatin is made up of DNA and proteins. The DNA coils around the protein and that structure is called a nucleosome. Each chromatid in Mitosis is made up of many strings of the DNA and proteins (nucleosomes) to form a half X. The chromosome is made up of two of the chromatids (DNA and proteins-nucleosomes)…

Turner's syndrome is a rare condition that affects females. It results when a sex chromosome (X chromosome) is either missing or partially missing. Turner’s syndrome can cause a lot of different medical problems such as short height, puberty failure, heart defects, learning disabilities and social adjustment problems. It is sometimes diagnosed before birth, during infancy or during their early childhood. Occasionally the diagnosis is delayed until the teen or young adult years in those who have…

It results in the sex chromosome being incomplete and results in an ‘XO’ in the 23rd pair instead of the regular ‘XX’. This results in the birth of a female with Turner’s syndrome – resulting in a short stature, infertility, heart defects and learning disabilities. As Turner’s syndrome is due to an incomplete meiosis division, it is random and not hereditary. This affects 1 in 2000 baby girls. During regular meiosis, in interphase the DNA is replicated once, the chromosomes will find their…

caused by abnormalities in one of the X-chromosomes. While turner syndrome’s symptoms may be mistaken at birth. However, the condition often isn’t diagnose until puberty. Although, with all other diseases most people don’t understand the dieses. So it goes untreated and the sighs are not taken seriously. Turner syndrome is a genetic cause. Females have two X-chromosomes. While the male have Y and X-Chromosomes. When a baby is born they are born with 23 chromosomes. To determine the gender of…

inherits the hemophilia on his X chromosome will be a hemophiliac. A girl who inherits the defective gene on one of her X chromosomes will be a carrier. Interestingly, she might transmit the defective gene to her children, but she won’t get the disease. (galegroup.com) They are called first-pregnancy hemophiliacs if their first child is a boy, and he inherits the disease. Boys have one X chromosome, and one Y chromosome, but girls have 2 X chromosomes, and one Y chromosome. (worldbook.com) She…

“People with autism spectrum disorder (ASD) demonstrate characteristics of impaired social interaction and communication abilities. These clients are unable to initiate conversations and fail to understand or observe nonverbal behaviors. Another identifier for someone with ASD is their use of repetitive and restrictive behaviors. A client with ASD will repeat the question being asked rather than answer it. The client will parrot or repeat one word or phrase that is spoken to them, also known as…

Daughters born to male carriers will inherit their fathers affected X chromosome and they will also be carriers. Sons born to male carriers will not inherit their fathers X chromosome and furthermore will not be affected by Fragile X. Although the level of these repeats varies for each person, boys seem to have more severe impacts then girls; this is because boys only have one X chromosome whereas girls have 2. The segment which repeats and causes this condition is called the “CGG…
