carrier of the full mutation and her offspring will be susceptible to Fragile X. Because some of the woman’s cells have Fragile X and some don’t‚ she is known as a mosaic. Males only have one X chromosome‚ which means that if there is a mutation on that chromosome‚ there is no other X for the cells to fall back on and the male will have the full disorder. Men who are carriers cannot pass the gene onto their sons because they give their sons the Y chromosome‚ meaning the mutation on the X will not be

Mutations can be good or bad‚ it depends on what type of mutations happens to that organism. Mutations can happen anytime or anywhere. It can be control or occur naturally. According to M.S.

“Yes‚ we are all individuals!” Can evolutionary psychology explain individual differences in personality? It is now a “rule” that “all human behavioural traits are heritable” (Turkeimer‚ 2000. cited in Pinker 2002). Pinker says that when psychologist Eric Turkheimer made this bold claim in 2000‚ he was encapsulating over 40 years of studies that overwhelmingly and robustly support this view‚ and only slightly exaggerating (Pinker 2002). Estimates of the mean heritability for the fundamental

person is born‚ their DNA is subject to many different mutations throughout their life. Some of which are inherited from their parents‚ they develop at birth or during their adulthood. Some of these mutations are harmless and can go unnoticed for your whole existence‚ while others can alter your health drastically. There are some mutations that are considered to be valuable‚ as well as a silent one which does not affect you at all. The mutations heard about most often are those that cause disease such

The etiology of brain cancer‚ like other malignancies‚ involves a complex interplay between epigenetic and genetic changes occurring during the natural history of tumor growth and development. Genetic changes accumulate in the form of mutations‚ activation of proto-oncogenes‚ or the loss of tumor suppressor genes that could promote tumor progression‚ invasion‚ and metastasis; this process provides a rational basis for targeting one or more critical genetic defects in cancer cells by using gene-mediated

Because it is not easy to test if females are carriers of the mutated gene‚ there are little to no stats on how many females actually carry the gene mutation. However‚ there are stats from a Korean institute‚ Yonsei University College of Medicine‚ reporting that only eight percent of female carriers actually display some symptoms of muscle weakness (Song TJ‚

more chromosomes. Departures from the normal set of chromosomes can refer to changes in the number of sets of chromosomes (ploidy)‚ changes in the number of individual chromosomes (somy)‚ or changes in appearance of individual chromosomes through mutation-induced rearrangements. They can be associated with genetic diseases or with species differences. Humans normally have 23 pairs of chromosomes- making 46 in total. One pair are the sex chromosomes- the ova and the sperm each carry 23 chromosomes

however. When we discuss genetic diversity it involves mutations‚ sexual reproduction‚ migration‚ and population size. All four of these factors add to the variety we see every day and are deeply intertwined and can be problematic. Before we begin to discuss the issues related to genetic diversity‚ we have to know exactly what genetic diversity is all about. It is a “term used to describe genetic differences among members of a population". Mutations occur when new genetic information is introduced to
