Question
12. Conduct an experiment in your class or dorm to see if low digit ratio correlates to athletic ability, aggression, antisocial behavior, or other traits.
13. Conduct an experiment to determine if the toe digit ratio provides the same results within individuals as measuring finger digit ratios.
14. Which of the characteristics mentioned are part of the genotype and which are part of the phenotype?
15. Google digit ratio and list other characteristics mentioned are part of the phenotype?
16. Hypothesize how a larger gene might be correlated to lower attraction between the encoded receptor protein and the hormone that it binds?
17. Suggest an experiment to test the hypothesis that low 2D/4D ratio correlates to an increased risk of developing male pattern baldness.
18. Research how the digit ratio varies among heterosexuals versus homosexuals.
Explanation / Answer
14. Characteristics of genotype:
Genotype refers to a particular gene or a set of genes carried by an individual.
Phenotype refers to actual description of physical characteristics like height, eye color, also overall health etc.
15. Digit ratios are utilized to determine the effects of prenatal androgen exposure a variety of phenotypic expressions. However, there is a paucity that systemically review the possible positive predictive value of 2D:4D in the development of AGA. It is the ratio of the length of different digits or fingers typically measured from the mid-point of bottom crease where the fingers join the hands to the tip of the fingers. Most commoly they indicate 2D(index finger):4D(ring finger) ratios.
Charateristics:
1. Most molecules and structures coded by the genetic material are not visible in the appearance of an organism, yet they are observable and part of phenotype.
2. Behavioral phenotypes include cognitive, personality, and behavioral patterns.
3. Some may characterize psychiatric disorders or syndromes.
18. A research that the ratio of the length of the 2nd and 4th digits (2D:4D) is negatively correlated with prenatal testosterone, has led to a number of studies of 2D:4D in homosexual and heterosexual men and women. The results have been mixed. Here we report mean 2D:4D in Austrian homosexual and heterosexual men. We found no significant difference between means for homosexual and heterosexual 2D:4D with values for both falling between 0.96 to 0.97.
