Comments on Cytology

Left breakpoint is at 20D1-20D2 and the chromosome is deficient for the rest of section 20.

Right limit of break 1 from inclusion of l(1)1Ac (FBrf0024685) Left limit of break 2 from inclusion of bb (FBrf0024685)

In combination with other aberrations

Fertile when in combination with Dp(1;Y)BSYy+and sterile in combination with Dp(1;Y)y+mal126 or Dp(1;Y)mal+.

Heterozygotes with Dp(1;Y)BSYy+ are fertile but sterile with Dp(1;Y)y+mal+ or Dp(1;Y)y+mal126.
