- Using the information and data from the 2 photos, answer the last question on the bottom of the second page. Please answer in detail and accurately. The question asks: “Did your results from the coin tosses support your prediction from the Punnett Square? Specify the data you used.”arrow_forwardI'm having trouble finding the dependent and independent variables of this scenaro: Average IQ scores for young school children are known to be 100 (SD = 15). However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy. Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies. Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children?arrow_forwardPlease solvearrow_forward
- A personality psychologist is interested if being a snob is heritable. To answer this question a personality psychologist recruits a huge sample of 2,593 identical twins and found that identical twins were similar in how snobby they were with an effect size of r=0.6. They also recruit a huge sample of 1845 fraternal twins and found that fraternal twins were also similar in how snobby they were with an effect size of r=0.4. Calculate the heritability coefficient for being a snob.arrow_forwardLooking at hairline (widow's peak = H) and ear shape (ear lobes = E)...

- Farmer John decides to increase the weight of the eggs produced by his chickens. The average weight of his eggs is 50 grams. He knows that the heritability of egg weight is 0.5. He selects for chickens producing eggs that are 64 grams. The expected average weight of the resulting eggs is: 59 57 54 55 56arrow_forwardA trait has a heritability of 0.15. This suggests: Question 5 options: The phenotypic variance is due entirely to genetic variation. The phenotypic variance is due entirely to environmental factors. The environment plays a much larger role in the phenotypic variance relative to genetics. Both genetic and environmental factors play similar roles in the phenotypic variation. Genetics plays a much larger role in the phenotypic variance relative to the environment.arrow_forwardThe effects of poverty, stress, racism, or socioeconomic status have not been conflated with the effects of genetics or ancestry.
