| AV38 |
mnDp66 (X;I); meDf2 X. |
C. elegans |
Produces 31% XO male self progeny; nondisjunction is correlated with a high frequency of achiasmate X chromosomes in oocyte nuclei, and a reduced frequency of X chromosome crossovers. meDf2 disrupts the function of the cis-acting X chromosome meiotic pairing center. meDf2/+ heterozygotes produce 4-6% XO progeny, so the presence of meDf2 can be followed in heterozygotes by this weak Him phenotype. |
| AV39 |
mnDp66 (X;I); meDf3 X. |
C. elegans |
Produces 32% XO male self progeny; nondisjunction is correlated with a high frequency of achiasmate X chromosomes in oocyte nuclei, and a reduced frequency of X chromosome crossovers. meDf3 disrupts the function of the cis-acting X chromosome meiotic pairing center. meDf3/+ heterozygotes produce 4-6% XO progeny, so the presence of meDf3 can be followed in heterozygotes by this weak Him phenotype. |
| AV40 |
mnDp66 (X;I); meDf4 X. |
C. elegans |
Produces 27% XO male self progeny; nondisjunction is correlated with a high frequency of achiasmate X chromosomes in oocyte nuclei, and a reduced frequency of X chromosome crossovers. meDf4 disrupts the function of the cis-acting X chromosome meiotic pairing center. meDf4/+ heterozygotes produce 4-6% XO progeny, so the presence of meDf4 can be followed in heterozygotes by this weak Him phenotype. |
| AV41 |
mnDp66 (X;I); meDf5 X. |
C. elegans |
Produces 32% XO male self-progeny; nondisjunction is correlated with a high frequency of achiasmate X chromosomes in oocyte nuclei, and a reduced frequency of X chromosome crossovers. meDf5 disrupts the function of the cis-acting X chromosome meiotic pairing center. meDf5/+ heterozygotes produce 4-6% XO progeny, so the presence of meDf5 can be followed in heterozygotes by this weak Him phenotype. |
| SP1027 |
mnDp66 (X;I); unc-1(e538) X. |
C. elegans |
WT strain. |
| TY2139 |
mnDp66 (X;I)/yDp14 (X;I); him-8(e1489) IV; yDf13 unc-1(e1598n1201) dpy-3(e27) X. |
C. elegans |
Heterozygotes are WT hermphrodites whose progeny include WT hermaphrodites, Dpy hermaphrodites (mnDp66; yDf13 unc-1 dpy-3), WT males and Dpy males. |
| TY2173 |
mnDp66 (X;I)/yDp14 (X;I); him-8(e1489) IV; yDf17 X. |
C. elegans |
The hermaphrodites are variable in phenotype, but most are Dpyish (small) and sick. Pick these hermaphrodites to maintain the strain, since healthier animals may have picked up a suppressor mutation or gone polyploid, etc. Strain gives WT males. |
| TY2175 |
mnDp66 (X;I)/yDp14 (X;I); him-8(e1489) IV; yDf17/unc-1(e1598n1201) dpy-3(e27) X. |
C. elegans |
WT hermaphrodites whose progeny include WT hermaphrodites, Dpy hermaphrodites (mnDp66; unc-1 dpy-3), Unc hermaphrodites (yDp14; unc-1 dpy-3), DpyTra hermaphrodites (mnDp66/yDp14; yDf17), WT males, Unc males, and Dpy males. There are 2 types of WT hermaphrodites in this strain which are indistinguishable unless you score their offspring: mnDp66/yDp14; him-8; yDf17/unc-1 dpy-3 animals will have many WT males progeny; but mnDp66/yDp14; him-8; unc-1 dpy-3 animals will have primarily dpy male progeny [mnDp66/yDp14; unc-1 dpy-3 XO animals are mostly dead, but there are some escapers of lethality]. Maintain by picking L4 WT hermaphrodites and checking for correct segregation of progeny. |
