Member of large scale dataset(s)
T(Y;2)L&S_set1

Set of Y;2 translocation stocks designed to allow generation of aneuploid animal by crossing two members of the set with breakpoints flanking the region of interest. For most regions, animals carrying both the duplication and the deficiency of the region between the autosomal breakpoints can be recovered and unambiguously identified.

T(Y;3)L&S_set1

Set of Y;3 translocation stocks designed to allow generation of aneuploid animal by crossing two members of the set with breakpoints flanking the region of interest. For most regions, animals carrying both the duplication and the deficiency of the region between the autosomal breakpoints can be recovered and unambiguously identified.

Comments

The tip of YL in Dp(1;Y)BSYy+ consists of a portion of region 16A near the B gene and the base of the X distal to bb. Comparative Genome Hybridization microarrays of chromosomes derived from C(1;Y)N12 (a translocation segregant derived from T(1;Y)N12, a reciprocal translocation between a normal sequence X and Dp(1;Y)BSYy+) indicate that the distal breakpoint of this X chromosome segment lies between Release 5 coordinate X:22228492 in fog and coordinate X:22384175 in stnA. In addition, genes proximal to stnA are duplicated in this segment. The proximalmost extent of this segment extends at least to coordinate X:22416503 in CG13865. No evidence has been see for a large duplicated segment encompassing the B-H1 and B-H2 genes in 16A using Comparative Genome Hybridization microarrays, but the resolution of the microarrays is not high enough to exclude the possibility of a small duplicated segment from the region.

In combination with other aberrations

The frequency of X-Y nondisjunction seen in Df(1)X-1/Dp(1;Y)BSYy+ males is increased by bbr10Δ3.1A-2, bbr10Δ3 and bbt13.2, but is not altered by bbr10Δ3.1A-1 or bbr12.

NOT in combination with other aberrations

YL in mitotic prophase same as that in BSY; YS carries the Hoechst-bright segment (Xhy+) found on YL of y+Y (Gatti and Pimpinelli, 1983, Chromosoma 88: 349-73).

Other Comments
 

A cross between D.melanogaster Ts(1Lt;YLt)Zhr/Dp(1;Y)BSYy+ males and D.sechellia females does not produce viable male progeny.

Dp(1;Y)BSYy+ can provide the missing functions of Df(1)X-1.

Yders (Y derivatives), originating from Dp(1;Y)BSYy+ chromosome, show a large influence on both the level and brood pattern of secondary non-disjunction. There is no correlation between secondary non-disjunction and non-random Yder distribution, indicating different mechanisms.
