Exercise
1:Patternsin Human Inheritance Traits
QUESTIONS

A. What
observationscan be made about the collected
and charted data?

B. Are
any two people exactly the same? If so, how
closely are they related?

C. Isyourhypothesis
supportedbythefindings?Whatstatisticaltoolmighthelpyoutomake
this decision?

D. Inthetotalsthatyourecordedin Table
1,didyoufindthatthenumberofdominantphenotypes
were
greater than, equal to, or less than the recessive
phenotypes?

E. Can
youexplainwhatpossible
genotypesaresuggestedbythispattern?Doesthisvaryby trait?

F. Would you
expect this outcome? Why or why
not?

G. Howwouldchanging
thelevelofthemappedtraitsaffectthechart?Forinstance,ifthealleles
for male or female were onthe
outer rim of the chart, rather
thaninthe middle,how wouldthe patternobserved differfrom
Figure 10-1?

H.
List several
other traits that humans have that are
governed by
genetics.

I. Would
your data vary
if you went to another part of the world, for
instance,
China?

J. Why might
collected data show
differentpatternsfor differentcultural
populations?

K. Wouldyouexpectthatthepatternwouldbedifferentifcollected100yearsagoinsteadof today? Why
or why not?

L. If you had percentages
of dominant and recessive
genes present for the total number of allelesofatraitfortheentireworld,wouldyouexpectthatpercentagetochangeover100years?
Why or why not?
