Which

 4.
You
are
studying
a
plant
in
which
the
color
of
the
flowers
is
determined
by
3
loci
(X,
Y,
Z).
 The
influence
of
these
loci
on
flower
color
is
equal
and
additive.
Each
locus
exists
as
either
 a
wild‐type
allele
or
a
null
allele.
Draw
a
histogram
of
the
possible
phenotypes
in
these
 flowers
when
grown
in
a
controlled
laboratory
environment.
Now
draw
another
histogram
 (or
modify
the
first
one)
for
these
same
flowers
grown
in
the
wild.

 
 
 
 
 
 
 
 5.
You
suspect
that
the
number
of
peas
in
a
pod
is
a
quantitative
trait
controlled
by
4
 distinct
loci
in
the
pea
genome
that
act
equally
and
additively.
You
cross
pure‐breeding
 peas
that
have
1
pea/pod
with
pure‐breeding
peas
that
have
8
peas/pod
to
generate
F1
 peas.
Next
you
cross
the
F1
peas
to
each
other
and
analyze
the
phenotypes
of
the
F2.
If
your
 hypothesis
is
correct,
about
how
many
plants
with
8
peas/pod
should
you
expect
to
find
if
 you
analyze
500
F2
peas?
 
 
 
 
 
 6.
Draw
a
Gaussian
curve
with
high
variance
and
one
with
low
variance.
 
 
 
 
 
 
 7.
Draw
a
scatter
plot
and
regression...
