| mxp = maxillopedia |
|
Gene:
|
mxp
|
|
Feature/structure:
|
Maxillary & labial palps
|
|
Linkage Group:
|
2
|
|
Origin:
|
spontaneous
|
|
Description:
|
• mxp/mxp causes transformation of the labial and maxillary palps into legs.

Gene:

Feature/structure:

Linkage Group:

( 2 ,
4 )
|
|
Origin:
|
Alexander Sokoloff lab, Berkeley, CA
|
|
Description:
|
• Antennal club and funicle fusion, giving antenna a shortened look.

Gene:
|

Feature/structure:
|
Antennae
|
|
Linkage Group:

2
|
|
Origin:
|
EMS, GA-1
|
|
Description:
|
• GOF. Funicle of antennae reduced via homeotic transformation towards palp. Sometimes behaves as an X-linked trait [upon outcrossing] but loses this property upon inbreeding, only to regenerate the property again upon outcrossing.

Gene:

mxp

Feature/structure:
|
Antennae and legs
|
|
Linkage Group:
|
2
|
|
Origin:
|
Gamma irradiation of Ga-1
|
|
Description:
|
• Funicle of antennae reduced via homeotic transformation towards palp. Legs are slightly shorter than normal, often with reduced sex patches on T1 legs.

Feature/structure:

Linkage Group:

|
|
Origin:
|
Ethylmethane sulfonate.
|
|
Description:
|
• GOF. Club and funicle of antennae reduced.
• Near-lethal with lethal mxp alleles
• Complements viable mxp.
• Homozygous stock is fertile.
• Other stocks balanced with Stm are only slightly leaky.
• Lab-S RFLP matches Stm RFLP in a clone from the A gene, so Stm probably is a Lab-S chromosome.
• No translocation found cytologically by Giovani Mocelin.

| T(2;9) mxp(Dch-1) = maxillopedia(Dachsund-1) |
|
Gene:

|
Feature/structure:
|
Antennae and legs
|
|
Linkage Group:
|
( 2 ,
9 )
|
|
Origin:
|
Radiation-induced.
|
|
Description:
|
• Dominant, gain-of-function [GOF]. Antennae & legs shorter than normal [partially transformed towards palp] in heterozygotes. Dch-1/Dch-3 heteroallelic adults have complete and dramatic transformation of legs into palps.

| T(2;9) mxp(Dch-3) = maxillopedia(Dachsund-3) |
|
Gene:
|
mxp
|
|
Feature/structure:
|
Prothorax.
|
|
Linkage Group:
|
( 2 ,
9 )
|
|
Origin:
|
Radiation-induced.
|
|
Description:
|
• GOF. Prothoracic legs are dramatically reduced. Remainder of prothorax is reduced to a lesser extent, presumably via a homeotic transformation toward labial or maxillary segment. Effect restricted to prothorax. Antennae are normal.
