Exercise: Patterns in Human Inheritance Traits
What observation scan is made about the collected and charted data?
Are any two people exactly the same? If so, how closely are they related?
Is your hypothesis supported by the findings? What statistical tool might help you to make this decision?
In the totals that you recorded, did you find that the number of dominant phenotypes were greater than, equal to, or less than the recessive phenotypes?
Can you explain what possible genotypes are suggested by this pattern? Does this vary by trait?
Would you expect this outcome? Why or why not?
List several other traits that humans have that are governed by genetics.
Would your data vary if you went to another part of the world, for instance, China?
Why might collected data show different patterns for different cultural populations?
Would you expect that the pattern would be different if collected 100 years ago instead of today? Why or why not?
If you had percentages of dominant and recessive genes present for the total number of alleles of a trait for the entire world, would you expect that percentage to change over 100 years? Why or why not?
