This study examined the effects of two definitions of chronic fatigue and chronic fatigue syndrome (CFS) on two personality traits, Neuroticism and Extraversion. Neuroticism also known as emotional instability. The hypotheses of the study were to associate emotional instability and extraversion traits with chronic fatigue and CFS in a genetically informative sample. Participants were monozygotic and dizygotic twin pairs with at least one twin member was chronically fatigue for at least six months. In Case-Control design, twins were given the subscales of Five Factor Inventory to evaluate the association between personality traits and chronic fatigue. Participants’ lifestyles, sex and age were also taken into consideration. Confounded evidence of shared genetics that both definitions of chronic fatigue were with higher emotional instability. However, lower extraversion was found to be associated with both definitions of fatigue, but was not confounded by familial factors. Chronic fatigue and CFS were associated to both emotional instability and extraversion. In contrast, emotional instability and chronic fatigue are linked to genetics mechanisms and the connection with extraversion may be related to both definition of fatigue. Keywords: Chronic fatigue syndrome, Personality, Neuroticism, Extraversion, Monozygotic, Dizygotic, Generic Introduction This research was focus on monozygotic-identical twin and dizygotic-non identical twin pairs to determine if there was a…

the current stage that they were in. Finally, the process was repeated as the zebrafish was going through its different stages. As a result, the stages and the in-depth descriptions were produced along with photographs and drawings to easily distinguish between the different stages. In the aftermath of reading the article, I learned that zebrafish have a yolk sac that contains yolk. The yolk is essentially nutrient storage for the zebrafish and promotes growth during the embryonic stage. A new…

Many people, at some point in their lives, wish for a twin brother or sister, but they don’t truly understand the difficulties and bond of having a life-long partner. Many twins have trouble identifying themselves as a single person. People they know and love compare the twins, often with drastic results; however, through it all, twins usually have such a close bond that it lasts through the ages. For singletons, it can be challenging to recognize the tight bond twins have, the struggle of…

Hypothesis The research focuses on the relationship between grit – “perseverance and passion for long-term goals” and the educational achievement, in comparison with other factors like personalities (Rimfeld, Dale, Kovas and Plomin, 2016, p. 780). The hypothesis of the research is that grit is a significant prediction of academic achievement. The researchers also want to understand more about the etiology of grit, its genetic and environmental origins. They want to know why individuals differ in…

The article ‘Sources of Human Psychological Differences: The Minnesota study of Twins Reared Apart’ includes the studies of Bouchard, Lykken, McGue, Segal and Tellegen which reveals psychological differences between monozygotic twins who were nourished separately and together. This study is derived from the Minnesota study which has conducted research over monozygotic and dizygotic twins from around the world since 1979 (Bouchard, Lykken, McGue, Segal, Tellegen, 1990). The monozygotic twins are…

make friendship a fine art, drink deeply from good books - especially the Bible, build a shelter against a rainy day, give thanks for your blessings and pray for guidance every day.(John Wooden). Visiting Both beautiful museums “ The Morgan Conservatory for Papermaking” , “Zygote Press” was amazing. Definitely an experience that will always be remember. Just walking into The Morgan it just influence you to want to come up with different peice works of your own. The paper making process was…

The zygote lasts for four days. On the fifth day, the cells become known as a blastocyst. The period will last for approximately two weeks, after this period of time the organism is known as an embryo; The Embryo: An Embryo is a fertilized egg that has begun cell division. An embryo grows arms and legs and begins to develop fingers and toes as it develops into a foetus it. In the eight week of pregnancy the embryo begins to form lungs, and its brain continues developing. At this stage, the…

The Zygote stage also known as the germinal stage is the first stage in prenatal development. The zygote stage begins as soon as the sperm meets the egg during conception. Once fertilized, the egg, also known as the zygote will start its journey to the uterus. This process itself takes about a week. Once the zygote has reached the uterus, after leaving the fallopian tube, it will began cell division and cell growth. After the rapid process of cell division and growth occurs, blastocysts will…

1 Month: The zygote grows rapidly to about one half inch. During this time, the heart starts beating and the veins and arteries is active. Organs, such as the brain, kidneys, and liver begin to grow. The microscope detects the eyes, ears, mouth and nose, but the sex is not detectable (Matorell, Papalia, & Feldman, 2014). 7 Weeks: The baby is one-inch long and organs begin functioning; the liver produces blood cells, the stomach produces digestive juices, and the heart has a regular beat. The…
