get started with visual phasing. We've identified our
recombination points and we've assigned those recombination
points. So, if you've been able to get this far on just one
your visual phasing. So, I hope this introduction to visual
phasing has been helpful. If you have any questions about
to go on to the next step. If you want to try this out

so happens it's B. But the next one is also a B and this last
and we have made a assignment as to which person that
one, well, that looks like that's a C. So what we've done
is we've gone through each one of these recombination points
have this pattern. This next one could be anything. It just
green to yellow so there's a change so AB is that and then
complete. We have gathered the data that we need in order to
down on BC it goes from green to yellow so what's common
it goes from green yellow AC well that is a common A and so

recombination point belongs to and with this, our setup is
what the next one is. Don't think that this pattern is
common. This next one is an A. We are going with an A B A B A.
Now if you start to think that hey there's a pattern and guess
common. This one is going to be a B because it has those two in
but because we're comparing that person with another person
look at is we need to look at where they are happening and so

This next one is going to be an A because it has those two in
that's an AB and it doesn't change on AC right here but
second one and we see that it's going from yellow to green so
recombination point right here okay we can see that we go from
what we're looking is which lines are changing and what's
comes in because I have this big long stretch of green and
then it had to go to yellow just for a little tiny bit then
then it's very shortly thereafter it goes from red to
assign the recombination points to a certain person now how do
the common person between those so if we look at this first
it's going to affect at least two lines at the same time so
a recombination point is going to affect one person at a time
you so that leads us now to step number four is we want to
a yellow to a red. So I didn't go from a green to a red. I
went from a yellow to a red which is perfectly fine. And
we assign those recombination points well what we need to
completed step number three let me clean this up just a bit for
it goes to this big red region. So I had to have this yellow
recombination points and so once you've done that you have
it goes back from red to yellow. Now it doesn't go to
yellow and we can see hey this is where that principle three

another point right here and so you can see I'm changing from

between those two. There has to be a transition point. Now, you
places so that what's passed on is actually a recombination of
cells and as part of that, the two chromosomes swap different
principle that we can learn from this is that the color
on down and then I can see this next point here there's this
green to yellow to green to yellow to green back to yellow
going to go through and draw these out. So if we're looking
between those colors. So now we're ready to actually start
drawing our recombination point lines and so remember our
versa. Now, the next principle and I know it's looking like we
can't go from green to red. You always have to go to yellow in

and then I have this big long stretch of just the yellow on
