Dam Genotype | Microphthalmia in del/del Offspring | |
---|---|---|
Present | Absent | |
Homozygote (del/del) | 17 | 1a |

Sire genotypes were del/+ for 12 microphthalmic dogs and del/− for 5 dogs. For non-microphthalmic dogs, sire genotypes were del/+ for 7 dogs and del/− for 4 dogs. The skewed distribution of maternal genotypes in this retrospective analysis is highly significant (p < 10−6, Fisher’s exact test, df = 1).
Chorioretinal hypoplasia with normal globe size.
