Dear Eleanor,
Sorry for the delay in this reply but I have been out of town for the past 5
days. Re: T(1;3;4)dsxM+R35. Not sure I can be as much help on this one, but
here is what I can say from the original drawing and notes.
1. The distal part of 3L (61-66C) is stuck onto something heterochromatic as
it sticks out of the chromocenter.
2. This distal part of 3R (98-100) also appears to be stuck onto something
heterochromatic as it also sticks out of the chromocenter.
3. 3R from the base to 98 is normal and stuck onto 98 is 66C and the rest of
3L (to 80C) which is attached to something; perhaps the 4th chromosome.
4. the obvious problem here is that while one can determine the euchromatic
breaks and the new euchromatic-euchromatic associations if there are multiple
heterochromatic breaks (as this rearrangement appears to have) one cannot
specify from salivaries what are the new euchromatic-heterochromatic
associations. Sorry I can't give you more definitive information, but this is
probably all that can be gotten from the type of observations that were made.
Sincerely, Bruce Baker
