|---|---|---|---|---|
| Parents (S-genotype)a | Observed ratio | Expected ratiob | χ2 (P-value) | |
| RS (S6S13′S26Sa) × Gold (S3S6) | 31 | 31:0 (S3:S6) | 1:1 | 31.0 (<0.0001) |
| Mont (S6 S13′SaSnull) × Gold (S3S6) | 55 | 55:0 (S3:S6) | 1:1 | 55.0 (<0.0001) |
| UF (S1′S4SdSnull) × Schmidt (S2S4) | 66 | 66:0 (S2:S4) | 1:1 | 66.0 (<0.0001) |
| Sure (S4 S13′SaSnull) × EF (S3S4) | 30 | 30:0 (S3:S4) | 1:1 | 30.0 (<0.0001) |
| EB (S4S6mSaSnull) × EF (S3S4) | 18 | 18:0 (S3:S4) | 1:1 | 18.0 (<0.0001) |

| EB (S4S6m Sa Snull) × Gold (S3S6) | 33 | 22:11 (S3:S6) | 1:1 | 3.67 (0.0555) |

a
The S-haplotypes being tested are underlined.
b
Observed ratios were tested for fit to the ratio expected if the shared S-haplotype is nonfunctional (1:1). If the shared S-haplotype were functional, it would not be inherited from the paternal parent.
