Table 1. Types of duplicated loci encountered in this study, expected segregation ratio per paralog, and expected segregation ratio when both paralogs are analyzed as a single locus, which is the case in this study.
Parental Genotype | Segregation Ratio Expected for Each Paralog in a Haploid Cross | Segregation Ratio Expected in the Offspring for a Haploid | Marker(s) Mapped in This Study | ||
---|---|---|---|---|---|
Paralog 1 | Paralog 2 | Paralog 1 | Paralog 2 | ||
aa | bb | all a | all b | all ab | None |
ab | ab | 0.5 a; 0.5 b | 0.5 a; 0.5 b | 0.25 aa; 0.5 ab; 0.25 bb | None |
aa | ab | all a | 0.5 a; 0.5 b | 0.5 aa; 0.5 ab | Paralog 2 |
aa | bc | all a | 0.5 b; 0.5 c | 0.5 ab; 0.5ac | Paralog 2 |
ab | ac | 0.5 a; 0.5 b | 0.5 a; 0.5 c | 0.25 aa; 0.25 ac; 0.25 ab; 0.25 bc | Paralogs 1 and 2 |
ab | cd | 0.5 a; 0.5 b | 0.5 c; 0.5 d | 0.25 ac; 0.25 ad; 0.25 bc; 0.25 bd | Paralogs 1 and 2 |
The type of duplicated marker was inferred from the observed segregation ratio and the alleles observed in the offspring generation.
