3. Hitchhiker's thumb is the ability to bend the thumb backwards at least 45° is due to a single dominate allele "T". Hitchhiker's thumb Straight thumb You sampled the 48 students in your Biology of Populations class, and determined that 15 individuals have thumbs that could hitch a lift (i.e. bend > 45°). a) Calculate the predicted frequencies of all the genotypes. b) Given what you know about the conditions required for the Hardy-Weinberg principle to be met, do you think this is a reliable prediction? Explain your answer.

Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.
