Suppose that we study a gene that has been linked to coronary heart disease. We find in a pilot study that in subjects with the C/ C genotype 20 events have occurred in 200 individuals over a period of 10 years, whereas in subjects with the T/ T genotype 30 events have occurred in 250 individuals in 10 years. Which genotype appears to be associated with a higher prevalence of heart disease?

Sex-linked crosses 4. Hemophilia is an X-linked disease, meaning that the gene that causes the disease is found on the X chromosome. Affected males only have to have one allele to have the disease (XhY), while affected females have to have two alleles (XhXh). Imagine that an affected male has children with an unaffected carrier female. a. What are the genotypes of the parents in this cross? b. Draw a Punnett cross to show the offspring of this couple. c....

A cohort study was undertaken to examine the association between high lipid level and coronary heart disease (CHD). Participants were classified as having either a high lipid level (exposed) or a low or normal lipid level (unexposed). Because age is associated with both lipid level and risk of heart disease, age was considered a potential confounder or effect modifier and the age of each subject was recorded. The following data describes the study participants: Overall, there were 11,000 young participants...

Suppose that you are interested in investigating the association between retirement status and heart disease. One concern might be the age of the subjects: An older person is more likely to be retired, and also more likely to have heart disease. In one study, 127 victims of cardiac arrest were matched on a number of characteristics (that included age) with 127 healthy control subjects. Retirement status was then ascertained for each subject. a) Test the null hypothesis that there is...

Intermittent use of antimicrobial socks does not decrease microbial prevalence in student athletes: a pilot study. Concordia University Faculty Scholarship Week 2018 Abstract (Edited) Microbial infections of the skin are common occurrences in modern life. Owing to their communicable nature, these infections are often more common in the realm of athletics and locker rooms, with many high profile cases. Many products, including socks, have been marketed as being capable of decreasing the negative aspects of microbes associated with the body....

An observational study of Alzheimer's disease (AD) obtained data from 15 AD patients exhibiting moderate dementia and selected a group of 10 control individuals without AD. AD is a progressive neurodegenerative disease of the elderly and advancing age is known to be a primary risk factor in AD diagnosis. Therefore, it was crucial for the study's credibility to examine whether the ages in the AD group might be significantly different than in the control group. The ages of the subjects...
