Abstract

BRIDGES AND ANDERSON (Genetics, 10, 418–441; 1925) have shown by genetic experiment that in Drosophila trisomic in respect of the X chromosome, the chromosomes concerned are in the two-strand stage at the time crossing over takes place, that any strand may cross over with any other strand and that “two strands which have crossed over with each other are as free to cross over with a strand from the third chromosome as with a strand from the original two chromosomes”.
