Emily and Jack were so excited at the birth of their baby Mark.“Jack, he’s just so perfect! Just one problem though, it looks like he has your hairline!” Emily teased her husband who, though only 32, was balding.“Emily, I spent all that time painting the baby’s room and I just hope that he’s not color blind like your father or he won’t be able to see it!” Jack responded.Both the pregnancy and delivery had been uneventful. But in the back of their minds, they really were worriedbecause their first child, Sean, died at the age of nine days.By the fifth day after birth, Mark began to have trouble nursing and by the seventh day he had completely stopped feeding. Emily and Jack were frantic because it seemed to them that Mark might also die.“What is going on with our family? Another sick baby?” Jack thought to himself.Emily and Jack rushed him to the emergency room. Although Mark's limbs were rigid and he had had a seizure, the examination showed no infection and his x-rays were normal. The…

- Does blood type determine your personality? In a study aimed at answering this question, a random sample of 100 adults was given a personality test, and a comparison was made between the scores on the introversion/extroversion scale and blood type (A, B, AB, О). (a) Is this an experiment, a retrospective observational study, or a prospective observational study? (b) Comment on the extent to which inferences can be drawn about a larger population and whether cause and effect can be established.arrow_forwardCharacteristics can be impacted by both genetic and environmental factors. What is one piece of evidence that can be used to show this?arrow_forwardIn the following experiment, what is the Independent variable and Dependent Variable? Dr. Honeydew would like to test the effect of chlorine on Beaker's hair color. To test this he pours heavily chlorinated pool water on the right side of Beakers head. To the left side of Beakers head he pours pure water. After doing this for several days, only the hair on the right side turns green.arrow_forward

So far, data suggests that such twins are more alike than researchers predicted; they frequently have similar personalities, mannerisms, habits, and interests. What general questions do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What abuses might occur if the studies are not evaluated critically and if the results are carelessly cited to support a social agenda?arrow_forwardWhich of the following genetic disorders is described by the following: Recessive sex-linked disorder.

- . Certain people are able to taste the chemical phenylthiocarbamide (PTC) when it is present in wet filter paper. These people are called 'tasters'. Others are unable to detect PTC and have the 'nontaster' phenotype. PTC tasting is an example of variation in sensory perception, and the genetic basis is thought to be rather simple. The ability to taste PTC is attributed to a dominant allele, denoted T, located on chromosome 7. The recessive allele is designated t. From analysis of pedigrees, 259 taster children and 278 non taster progeny were observed where one parent was heterozygous and could 'taste' PTC and the other parent was a 'nontaster'. Does this data set support the suggestion that his variation is due to a simple Mendelian pattern?arrow_forwardImagine that genetic technology advances to the point where the genetic profile of an individual can be easily obtained, and that we have a full understanding of how genes interact to influence our health. Based on this genetic information alone, how reliably do you think we would be able to predict a person's chance of getting a specific disease? Where do you think this type of genetic profiling would lead with respect to selection of offspring or genetic superiority?arrow_forwardThe nature versus nurture debate is one of the oldest issues in psychology. The debate centers on the relative contributions of genetic inheritance and environmental factors to human development. Discuss four (4) environmental factors that may affect the growth and development of humans and their educational implicationsarrow_forward
