Detailed Description
Statement
Reference

Heterozygous females show precocious nuclear envelope breakdown in stage 12 oocytes.

Heterozygosity for mtrmexc13 results in elevated X (49.0%) and fourth (29.0%) chromosome nondisjunction in In(1)FM7/X ; svspa-pol females compared to controls. The level of X chromosome nondisjunction in heterozygous mtrmexc13 females carrying two normal sequence X chromosomes is only 3.1%, while the frequency of fourth chromosome nondisjunction in these females is 31.0%.

Statement
Reference

The "exc13" chromosome (which carries the exo70exc13 and mtrmexc13 alleles) shows recessive semi-lethality; less than 50% of the expected number of homozygous adults eclose out of their pupal cases and those that do die within 1-2 days of eclosion.
