From: Imprinted gene expression in hybrids: perturbed mechanisms and evolutionary implications
Mules | Progeny of a male donkey and a female horse |
Hinnies | Progeny of female donkeys and male horses |
Peromyscus | North-American genus of mice (‘deer mice’) |
P. maniculatis (‘M’) | A species with polygamous mating behaviour |
P. polionotus (‘P’) | Species with apparent monogamous mating behaviour |
P × M | Hybrid produced by a female P. maniculatis paired with male P. polionotus |
M × P | Hybrid produced by a male P. maniculatis paired with female P. polionotus |
Mus musculus (‘MU’) | Widely studied mouse species |
M. spretus (‘S’) | Species related to M. musculus, in the Mediterranean, that diverged over one million years ago |
(MU × S) F1 | Hybrid produced by a male M. musculus paired with a female M. spretus |
(S × MU) F1 | Hybrid produced by a female M. musculus paired with a female M. spretus |
C57Bl/6J (‘B’) | A mixed M. M. domesticus laboratory mouse inbred strain |
CAST/EiJ (‘C’) | M. M. castaneus laboratory mouse strain |
Arabidopsis | Genus of small flowering plants of the mustard family (Brassicaceae) |
A. thaliana, A. arenosa | Related Arabidopsis species used in imprinting studies |
DMR | ‘Differentially methylated region’: here, a sequence element with allele-specific CpG methylation |
ICRs | ‘Imprinting control regions’: essential regulatory DMRs, which have germ line-derived, mono-allelic DNA methylation and mediate imprinted gene expression in cis. |
D–M model | Dobzhansky–Muller model |
A m A p | Alleles derived from the mother and father, respectively |
