1. Chromosome 1 is involvod in 17, chromosome 2 involved in 20, chromosome 3 in 22, chromosome 4 in 18, chromosome 5 in 16, chromosome 6 in 14, chromosome 7 in 11, chromosome 8 in 11, chromosome 9 in 13, and chromosome 10 in 16 different reciprocal translocations. Most of these translocations have been obtained in a homozygous condition.
Note: Anderson has kindly offered to furnish any of his translocations to anyone who can use them as a tool in his research. The complete list of these interchanges (reciprocal translocations) will be listed in the next corn letter. Anyone desiring an interchange should write to Anderson and explain his needs to him.
