This suggests that a genetic factor is involved. MZ twins share 100% of their genes; DZ twins share 50% of their genes. If genes are a factor we would expect more identical twins to share the disorder than non-identical. Rosenthal took a case study which had a set of female quadruplets. They all developed schizophrenia although the onset and symptoms were very different.
During cell division of the cells reproduction, the 46 chromosomes should be divided into half having 23 chromosomes in each new cell. With the new cell having an extra or lacking chromosome, nondisjunction abnormalities occur. Down syndrome, being the most common abnormality, occurs with the presence of extra chromosome 21. It occurs in about 700 to 800 births. Langdon Down first described it but still with an unknown case.
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. White students had a clear picture of the existence of their race through many teachings. Many important facts that are taught portray white people as key figures. I can go into a book shop and count on finding the writing of my race represented, into a supermarket and find the staple foods that fit with my cultural tradition, into a hairdresser’s shop and find someone who can deal with my hair: White people do not have to go to specialty shops to find food or clothing that fit into their cultural tradition. They can be found at any supermarket or department store.
Gottesman (1991) investigated twin studies of monozygotic and dizygotic twins. He summarized 40 concordance studies and found that when one of the twins was diagnosed with schizophrenia, monozygotic twins showed a 48% concordance rate over a 17% concordance rate in dizygotic twins. Due to the monozygotic twins sharing 100% of their DNA and dizygotic sharing only 50%, this shows that genetics are very likely to play a role in someone developing schizophrenia. However, due to concordance rates not being 100% in MZ twins, it also suggests that some environmental factors must play a role too. Loehlin and Nichols (1976) suggested that the high concordance rates in MZ twins is most likely to be due to the fact they will be treated very
or the X-linked uric aciduria enzyme defect. Do you have any questions before we begin? Elizabeth: Yes actually, how will this affect my baby? Chloe: Well, before I can explain how your baby may be affected I need you to have an understanding of the disease, so let’s start with the basic information. Elizabeth: Alright, what do I need to know?
T/F The ecological movement has sensitized us to the interdependence of living systems, and the new sciences of sociology, anthropology, and psychology have helped us understand the interrelatedness of human social systems.

Celiac disease is an inherited autoimmune disorder for which there currently is no cure. Celiac disease is currently considered the most under-diagnosed “common” disease in the United States. Diagnosis can be made through a simple blood test, but symptoms are so varied they often mask themselves as other disorders and end up misdiagnosed.
An estimated 100,000 Americans have a neurofibromatosis disorder, which occurs in both sexes and in all races. Neurofibromatosis is an autosomal disorder, which means that only one copy of the affected gene is needed for the disorder to develop. Which means if only one parent has neurofibromatosis, his or her children would have a fifty percent chance of developing the condition as well. The severity in affected individuals can vary; this may be due to variable expressed. About half of the cases are due to de novo mutations and no other affected family members are seen.
