The daughter of the same woman is unlikely to be color blind unless her father is color blind; however she retains a 50% chance of being a carrier for the defective gene. BLUE COLOR BLINDNESS Blue color blindness (often referred to as blue yellow color blindness) is extremely rare, so rare that only 5% of color blind people suffer from it. Unlike red green color blindness, the chance of having blue color blindness is equal in both men and women as the gene is found on a different chromosome ( chromosome 7). This gene is shared equally by men and women and blue color blindness comes from a mutation of this gene. COLOR BLINDNESS BY NATIONALITY One might expect the percentage of affected people to be relatively constant in all countries however this is far from the truth.
P2 Describe two studies in psychology. Solomon Asch - Conformity Experiment (1951) Asch wanted to find out if a group of people would conform to the wrong answer following people who had already but there hand up even though the correct answer was very obvious. It was used with a line graph and you had to say which line was the tallest out them all. Asch conducted an experiment to investigate the extent to which social pressure from a majority group could affect a person to conform and follow what they do. Asch used a lab experiment to study conformity; he got 50 males to come and do the experiment and used 7 people who were confederates, the confederates had agreed in advance what their responses would be when shown with the line task.
The results were “surprising” since on average, every single woman in the different groups lost weight, but most surprisingly women in the exercise groups did not lose statistically significant more weight than the no exercise control group. Cloud even mentions that some of the women in the exercise group gained weight (up to ~10 pounds). Cloud suggests– drawing his knowledge from a study published in 2000 in Psychological Bulletin – that “[…] self-control is like a muscle: it weakens each day after you use it.” thus perhaps implying that this is a result of evolution; some are
Let us then take 4 urban schools from a Northern California East Bay district as examples. In 2005, two of these schools were labeled as “dropout factories”, where approximately 20% or less of 9th graders were promoted to the 12th grade 4 years later, as determined by research performed by John Hopkins University. The other two schools displayed the inverse relationship with “promoting power”, as they reported over 90% of 9th graders being promoted to the 12th grade 4 years later. While there are many differences between these schools, let us only look into 1 for the moment: curriculum. For the 2 schools labeled as “dropout factories”, curriculum and instruction information on their webpage only refer to the California Content Standards and mandated district requirements.
B B Bb | Bb | Bb | Bb | b b All (Bb) heterozygous genotypes are expressing the phenotype of black eyes. If we do another cross for F2 generation we will find 2 heterozygous black eyes, 1 homozygous black eye and 1 homozygous brown eye among the offspring. The punnet square is as follows: B b BB | Bb | Bb | bb | B b The genotypic ratio is – 1(BB):2(Bb):1(bb). The phenotypic ratio is – 3:1. DROSOPHILIA MELANOGASTER AS A MODEL FOR STUDYING GENETICS Drosophila melanogaster also known as the fruit fly is used commonly in the study of genetics.
Of these subjects, 75% of them changed their answers to the majority vote at least once. When under the influence of peer pressure, the subjects accepted the majority and conformed 36.8% of the time. 25% of the individuals who partook in the experiment did not conform at all. Many variables within the experiment made the conformity rate fluctuate. These variables among others were unanimity, and when faced with an opposition of only 2, minority subjects “accepted the wrong answer 13.6 per cent of the time.
Diamond and Sigmundson’s completed a study of a little boy named David who was a twin who lost his penis during a circumcision so at the age of 17 months old he was then raised as a girl named Brenda so that he could feel like he fitted in. The results of this study were that he started showing masculine traits and decided he wanted to be changed back in to a boy. This study supports the biological approach towards gender as it shows that Bruce developed masculine traits because of his biological sex (male). However, David could have learnt these masculine traits during his first 17 months of being male as his gender was resigned after a child starts learning and developing. He could have also picked up some of these traits from his twin brother.
After doing some research and evaluating the reasons I found an interesting statistic in which the American Scientist by telegraph (UK) states: Researchers from King's College London studied 45 childhood characteristics in 6,759 pairs of identical and non-identical twins across the UK, to determine whether their genes or their environment was more important. A new series of "nature-nurture" maps produced by the team revealed that some areas are "environmental hotspots" for particular traits, but in other places the same attribute is mainly governed by genetics. When a child is born it inherits either its mothers or father genes and maybe some characteristics. These genes are passed down through generations, for example: Let’s say a father has anger management problems, it is very likely that a child may develop that as well or their might have been history of anger problems in the family. Or another example is a cancerous chromosome, in which some children can inherit from their parents.
ADHD stands for attention deficit hyperactivity disorder. It has been recorded that it is unknown on what exactly causes ADHD, but it does say that genetics are partly a cause of it. The rate for boys and girls are 5.5% girls and 11.2% boys have ADHD (www.statisticbrain.com/attention-deficit-disorder-adhd-statistics). Experts say that ADHD has a strong genetic component; however they think that the neurotransmitters are different in an ADHD person (What Causes ADHD...). Studies say that it can occur if the mother did certain things while pregnant such as smoking or drinking.
2. Re-read the author’s list of 46 examples of white privilege. Select five examples that seem the most significant in helping you to understand that white people are privileged. Explain your selections. I can be sure that my children will be given curricular materials that testify to the existence of their race: I worked in education for 10 years and the only time I really noticed a focus on the study of people of different cultures was when it was Black History Month, or when Social Studies focused on Native Americans or slavery.
