You are a geneticist. A color-blind man (XbY) and a non-colorblind woman (XBXb) seek your advice because they are worried about passing on the colorblind gene to their future offspring.  You generate a Punnett square to predict the phenotypic and genotypic probabilities of their offspring (see included image). You explain to them that the color-blind trait is a sex-linked trait where: XX is female, XY is male, B is not color-blind, b is color-blind. The genotype of a female that is color-blind is XbXb.  The genotype of a male that is not color-blind is XBY, the genotype of a male that is color-blind is XbY. From the image included and with what is known, what are the probabilities that they will have non-colorblind children, color-blind sons, color-blind daughters, and carrier daughters?

Let’s assume that we want to estimate the effect of tech innovation on individual wealth in a nation. We can measure individual wealth in a nation with GDP per capita. We can measure tech innovation with the number of patents or the number of science journal publications. In addition, we want to measure the Covid-19 pandemic effect on individual wealth as well. Therefore, we construct the dataset as follows: Patent: the number of patents in a country GDPcapita : GDP per capita = GDP/population GDPgrowth: GDP growth rate SCJournal: the number of scientific journal publications HighTechExport: the share of high-tech export in GDP Unemploy: Unemployment rate Covid: 1 data comes from 2020 (during the pandemic); 0 data comes from before the COVID-19 pandemic period. Here, GDP per capita is: ________________.

A school-age child has a history of chronic otitis media and is seen in the clinic with vertigo. The primary care pediatric nurse practitioner notes profuse purulent otorrhea from both pressure-equalizing tubes and a pearly-white lesion on one tympanic membrane. Which condition is most likely? Cholesteatoma Correct Mastoiditis Otitis externa Otitis media with effusion

A 15-year-old female reports fainting at school in class on two occasions. The adolescent’s orthostatic blood pressures are normal. The primary care pediatric nurse practitioner suspects a cardiac cause for these episodes and will order which tests before referring her to a pediatric cardiologist? 12-lead electrocardiogram Correct Endocardial biopsy Tilt table testing Treadmill exercise testing
