Genetic mapping information
Comments

Southern blots and in situ hybridization mapped the T(1;4)BS breakpoint 15 kb distal of the Dp(1;1)B breakpoint.

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.

    Position-effect at B more extreme than in Dp(1;1)B. Homozygous female viable homozygous female fertile. Male viable but with reduced fertility (Novitski, 1970).

    T(1;4)BS substantially reduces recovery of independently assorting autosomal free duplication: chromosome shows meiotic drive. The effect of chromosome pairing sites on meiotic drive by T(1;4)BS is linked to the Ts(1Lt;4Lt)BS segregant.

    (McKee, 1987)

    Used by Stern in cytological demonstration of crossing over (1931, Biol. Zentr. 51: 547-87). XP4D from T(1;4)BS used by Lindsley and Sandler <up>1963, Methodology in Basic Genetics (W. J. Burdette, ed.). Holden-Day, Inc., pp. 390-403</up> in construction of compound-generating BS duplications. Reciprocal products of meiosis in male not recovered with equal frequencies (Novitski and Sandler, 1957, Proc. Nat. Acad. Sci. USA 43: 318-24; Zimmering, 1960, Genetics 45: 1253-68; Zimmering and Barbour, 1961, Genetics 46: 1253-60; Zimmering and Perlman, 1962, Can. J. Genet. Cytol. 4: 333-36; Novitski, 1970, D. I.
