Chromosome

recessive fashion; however, it may also occur in people from families without a known family history of the condition” (“Duchenne Muscular Dystrophy”). During offspring, parents pass on two sets of chromosomes each. A mother always passes on an X- chromosome, letting the father pass on a Y- chromosome, deciding the gender of the child. The flawed gene passed on by the mother does not have to date back to ancestral connections, either because the family might have not known about the disease and…

Twenty- three chromosomes from each parent are passed down to the offspring. Hereditary cancer starts here. When the chromosomes start to split, the ones affected by cancer will get the chromosomes mixed up. This causes chaos for the rest of the chromosomes. If one of the chromosomes has a cancer gene in it, it will be passed to the offspring along with the others. This means the cancer gene is in…

Other than sex differentiation at birth there is little evidence for any further differentiation in men and women due to sex chromosomes. It does not follow that chromosomes should be an explanation of gender identity either since there is no reasonable correlation. While chromosomes do influence sexual organs, what people usually refer to as “biological sex”, gender and gender norms are a product of the society in which they are expressed. Our western…

Inherited traits put growth and development into action in not only individual organisms but also the evolutions of species over time. Humans wouldn’t have evolved to who we are now if it wasn’t for inherited traits. In fact all species have adapted and evolved to be unique and distinct. For example a hummingbird that has adapted to have longer bills to be able to reach inside a flower to get nectar. Hummingbirds could die out from having short bills so they evolved throughout generations. These…

Hemophilia is a medical condition in which the ability of the blood to clot is severely reduced causing the sufferer to bleed severely from even a slight injury. There are four types of Hemophilia which are Hemophilia A-Also called classic hemophilia, it is four times more common than Hemophilia B, and it occurs when factor VIII levels are deficient, Hemophilia B-Also called christmas disease, it occurs when factor Xi levels are deficient, Hemophilia C-It occurs when facts of XI levels are…

With today’s technology it is much easier to test a baby’s chromosomes. After giving birth, chromosome analysis can be done via blood test, before birth via prenatal testing i.e. Amniocenteses or Chorionic villus sampling. This topic is controversial and there are mixed feelings if the testing should be done. I feel that doing prenatal testing in advance is unnecessary because generally, people do not terminate a pregnancy even when they hear that the fetus might have chromosomal abnormalities.…

Genetics are something that everybody has, they are the reason why people look the way they look. Genetics is the review and the variety of acquired attributes that make up new life. Each kid acquires qualities from both of their natural guardians. Some of these qualities might be physical; hair, eye shading or skin hues, and so forth. On the defeat a few qualities may convey certain sicknesses. Every quality is a bit of hereditary data and all DNA in the cell make up the human genome. The…

Gender selection is a technique that allows you to choose the gender of your future child by separating sperm carrying X chromosomes from the ones carrying Y chromosomes, and creating an embryo from the female egg and the preferred (X or Y) chromosome. This procedure is very useful in medical cases, as a way to lower the chance of a child inheriting a gender related genetic disease and disorders. For example, Rett syndrome is a brain development disorder that causes loss of control in the hands…

Greider and Jack W. Szostak for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase. A telomere is a stretch of DNA which has repetitive sequences of bases at the ends of chromosomes. When scientists started to develop knowledge on how genes are replicated, they realised that on one of the double strands of DNA cannot be replicated at the very end of the strand and due to this every time a cell divides its chromosomes gets shorter but telomeres explain how…

- Genetic testing is a medical assessment that detects any changes occurring in your genes, proteins or chromosomes. ("What Is Genetic Testing? - Genetics Home Reference." U.S. National Library of Medicine. National Institutes of Health, n.d. Web. 29 Nov. 2016.) - It is used to rule out any genetic condition as well as it can be used to determine a person’s chance of developing a genetic disorder.
