It is proposed that the inversions carried by SD chromosomes from nature act to eliminate recombination and thereby balance the distorting elements of the SD complex.

Lethal and female and male sterile when homozygous.

Notes on Origin

Associated with: In(2R)NS. The chromosome carrying both In(2R)SD5 and In(2R)NS is referred to as 'SD-5'.

The chromosome carrying In(2R)SD5 also contains In(2R)NS, and is referred to as 'SD-5'.

Associated with: SD-5.
