Figure 3

Polytene chromosomes from the strain T(Y: bp+)-7. Thick arrows show the ectopic paring between the telomeres of the V and III chromosomes. a) Thin arrow shows the autosome breakpoint; in this case the intact chromosome III is taken part in the ectopic pairing. b-e) The autosome fragment of the Y-A chromosome is taken part in the ectopic pairing. f) Normal ectopic pairing between chromosomes V and III from the wild-type strain. Bar = 10µm
