Genotype
MGI:4412285

hm1

• Allelic Composition: Hxd/Hxd
• Genetic Background: Not Specified

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

prenatal lethality, complete penetrance ( J:14124 )

• the number of resorption sites found in heterozygous females mated to heterozygous males suggest death of homozygous embryos realtively early in development

Genotype
MGI:4412283

ht2

• Allelic Composition: Hxd/Hxd⁺
• Genetic Background: Not Specified

limbs/digits/tail

abnormal hallux morphology ( J:14124 )

• more than 50% of mice have partial or complete duplication of the hallus of the rear feet

preaxial polydactyly ( J:14124 )

• limited to partial or complete duplication of the hallus of the rear feet

• more than 50% of mice are bilaterally affected

• there is reduced penetrance of this trait; fewer than expected affected mice are seen at birth and weaning from matings of heterozygous mice to wild-type mice and studies show no evidence of embryonic death
