1. WHICH OF YOUR genotypes were you able to better determineafter consideration of phenotypes of your parent and siblings?
2. WHY DON’T RECESSIVE traits always eventually disappear frompopulations?
3. WHAT FRACTION OF recessive alleles are “hidden†inheterozygotes for each of the eight single-gene traits that youstudied?
4. HOW MANY GENERATIONS would it take to eliminate at least 95%of the alleles for the recessive gene for the inability to tastePTC is a tyrant eliminated those who could not taste PTC from everygeneration before they could pass on their recessive alleles?
5. WHY MIGHT YOU expect the locus that governs lactosetolerance/intolerance to not be in Hardy-Weinberg equilibrium?
6. WHAT MAY HAVE led to errors in your determining you totalridge count and how confident are you in the reliability of theheritability for this trait that you calculated?
7. IQ IS ANOTHER characteristic that is apparently heavilyinfluenced by both genes and environment. What other humancharacteristics are likely to fall into this class?
