[nabs-l] punnett squares

Oh yeah! The only problem with that solution, Josh (and BTW, I 
did the same thing in bio last year, that is, my IA, 
instructional assistant, Brailled them for me) is when the 
teacher asks you on an assignment or test or something to 
actually make the punnet square from scratch.  Then you'd have to 
use a Brailler.

Or just ask them to braille them out for you, that's what was 
done for
me.  Took a while for me to get it, but I think the teacher said 
I was
one of the few that actually got the concept.  Btw, brings back
memories, Ashley.  :)

 Hi,
 You cannot do punnet squares in a linear form on a braille note.  
Use a
 brailler; yes do them on graph paper or make the  squares 
tactilly somehow.
 I used large print.  But same concepts apply.  Punnet squares 
are a grid of
 squares.  So picture a small table.
 I believe they are two rows, two colums as  I recall.  You put 
two
 letters in each square to represent genes.
 I really hope I explain the representation right as its been 
years since bio
 for me.
 If you bring two of the same letters together, its homozygous.  
Note the
 capital or lowercase letters as I write.
 Capitals are dominant and lower case are recessive.
 Example:  bb for recessive brown eyes.
 Example B B for dominant blue eyes.

 If you have different case of letters, its hetro zygous.
 You look at the top letter and letter on the side to put the 
letters in the
 square.  For instance a Large P for dominant gene on top and on 
the side a
 small O for recessive gene.  So you write P O in the block.
 Quite hard to explain without showing you.  I suggest you ask 
your teachers
 for clarification.

 This video might help; maybe if you watch it with a sighted 
person they can
 help you understand it.

 Hi,
 I am really, really, really confused with Punnett squares.  So I
 have some questions about them.

 First, to make them, should I use a Perkins Brailler? I do all 
my
 other science work, as well as for my other subjects except math
 homework, on my Braille-Note Apex.  Would a Perkins Brailler be
 better?
 Also, do you hand-make the grids? I have some graph paper from
 math that I might be able to use, but hand-making them might be
 easier.
 So can you please explain how to make a Punnett? Also, it would
 really help if you could additionally tell me how you learned
 Punnett squares because I'm really confused.
 Thank you for your time.  Attached to this email is a copy of 
the
 questions from the worksheet that I am supposed to do for
 homework.  Ignore Problem 10 and any others that you don't have
 to solve.
 Sincerely,

 Vejas
