    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…

    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…

    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.
