Y chromosome

Y chromosome is a sex determine chromosome among many species including modern humans. Modern studies in genome suggested that Y chromosome arose from the accumulations of mutations of other chromosomes and have some special genes on it which determine the gender of the carrier; however, some non-mammalian animals carry the Y chromosome even if their genders are not determine by the appearance of the Y chromosome. The Y chromosome works differently on the mammalian and non-mammalian so in this paper when an aspect about Y chromosome is brought up, it well be discussed in both mammalian (use human as example) and non-mammalian (use Drosophila as example) case. The paper will mainly focus on three point: how Y chromosome originated; the function…

same time. This again may have been due to him having very traditionally views that women should complete household chores and he should only work. Therefore, he may have thought that if they wanted him to do both he would be able to cope but then during the two week period found it to stressful. Another influence of gender is the chances of getting an illness because of them being female or male. Males are more likely to get the following diseases or conditions: asthma, hypertension, diabetes,…

Turner syndrome, also known as TS and gonadal dysgenesis, is a chromosomal deficiency affecting over two million women that occur when two of the X chromosomes in a female’s DNA are either incomplete or missing entirely. It usually becomes apparent when a female is only a few years old, or even shortly following her birth. The missing genetic material of the X chromosome keeps the female body from maturing on its own. Because Turner syndrome is different for every female and an individual…

behavior are inherited as Galton once said. Therefore, in order to prove if nurture is the real reason behind a person’s decisions, it is necessary to investigate if nature also plays part of people’s destiny. One of the first theories in 1960s was that men that committed crimes had an extra Y chromosome. Initially, the idea that the Y chromosome defines man, and that men are more aggressive than women, resulted in the theory that an extra Y chromosome would increase males’ aggressiveness. The…

supported by the John Hopkins Medicine and a grant from the Maryland Department of Health and Mental Hygiene (Using OMIM, n.d.). Two Sex Chromosome Abnormalities The first sex chromosome abnormality chosen was Down Syndrome. Down Syndrome, also known as Trisomy 21, is a form of mental retardation caused by the triplicate state of the critical portion of chromosome 21 (TRISOMY 21, n.d.). The risk of having an infant with Trisomy 21 increase with maternal age. The if a 1 in 1,000 chance by age…

In people without Turner syndrome, they have two sex chromosomes. For males, that would be one X chromosome and one Y chromosome. For females, they would have two X chromosomes. For females who have Turner syndrome, they have one normal X chromosome and the other is either missing or structurally altered. The chromosomal abnormality occurs as a random event during the formation of reproductive cells in the affected person’s parent. When a pair of chromosomes fails to separate during the…

SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to…

Duchenne Muscular Dystrophy In this world, there are many diseases that are being caused by the X chromosomes or the Y chromosomes. Some of the diseases could be passed down from generation onto the next because it is gene and some of the diseases can be treated and which later on causes for it to make it worse. The diseases that would always be there would be Down Syndrome, Huntington’s Disease, Hemophobia, and many more. As you can see, this paper is going to be able a genetic disease that is…

organism 5. The new gene is then passed on from one generation to the next. (University of Nebraska) Each person has 46 unique chromosomes…

day, I struggle knowing I have a genetic disorder; Turner Syndrome. Turner Syndrome, or TS, is a genetic, chromosomal disorder in which a female is born with only one X chromosome (the 23rd pair). This affects the development in women (the disease can only occur in women). The most common way a female can get TS is by monosomy, which means an X chromosome is completely…
