Popular misinterpretations of the use of race in genetics also continue to fuel racist beliefs, so much so that, in 2014, a group of leading human population geneticists publicly refuted claims about the genetic basis of social differences between races ( 20). Cystic fibrosis is underdiagnosed in populations of African ancestry, because it is thought of as a “White” disease ( 19). For example, hemoglobinopathies can be misdiagnosed because of the identification of sickle-cell as a “Black” disease and thalassemia as a “Mediterranean” disease ( 10). As a result, racial assumptions are not the biological guide-posts some believe them to be, as commonly defined racial groups are genetically heterogeneous and lack clear-cut genetic boundaries ( 10, 11). One reason is that phylogenetic and population genetic methods do not support a priori classifications of race, as expected for an interbreeding species like Homo sapiens ( 11, 18). It's exciting to see a paragraph like this in the world's most prestigious scientific journal: This does not mean that these categories are not real, but that these characteristics are not innate, fixed, "natural" properties of human beings instead the idea is that how we perceive and interact with people according to these categories is contested, time-dependent and malleable.

I have often taught classes which include the idea(s) that the identity characteristics of sex, gender, race, sexual orientation are socially constructed. It is time for biologists to find a better way." In an important article titled " Taking race out of human genetics" published in Science magazine today, a team of researchers argues that "the use of biological concepts of race in human genetic research-so disputed and so mired in confusion-is problematic at best and harmful at worst. That Cedrick got every single point on the exam is quite amazing, and inspiring! And I have taught the material on this exam to my students many times.

Lincoln High School Principal Jose Torres said Cedrick's achievement was inspiring.I love this story! Lincoln High School is roughly 2 miles from my house and as a professor of Mathematics I interact with students who have taken AP Calculus exams before coming to my college. “I'm speechless,” Lilian Argueta said Sunday. Lilian, a licensed vocational nurse, works two jobs at nursing homes, and Marcos is a maintenance worker at one of those nursing homes. He is the son of Lilian and Marcos Argueta, both of whom came to the United States as young adults - she from the Philippines, he from El Salvador. The White House Science Fair, hosted by the president, features projects, designs and experiments from students across the country and celebrates students who excel in science, technology, engineering and math.Ĭedrick's story has made headlines around the world since his score was announced by the Los Angeles Unified School District last week. The Los Angeles Times r eports about the reaction to Cedrick's achievement:Ĭedrick - a quiet, humble student who is quick to thank his teachers and parents for his success - said he'll join the president at the fair “if his offer still holds.”
