Abstract
The chromosomal abnormality in Drosophila, known as trans-location I, is located at approximately 76.9 on the 3rd chromosome. Its presence does not affect the crossover values for the first 45 units in the left-hand end of the chromosome. To the right of this point, the % of crossing over progressively decreases as the locus of translocation is approached, reaching its minimum of less than
