Fig 4. Phenotype characteristic of second-generation crossbreds lambs (F2 and BC1).

Fig 4

(A) The F2 offspring resulting from in-breeding with the homozygous variant (GG) genotype for Booroola/FecB mutation (OAR6: 29382188A>G, NC_019463.1 of genome assembly Oar_v3.1). (B) The F2 offspring resulting from in-breeding with the homozygous variant genotype (AA) for MSTN mutation (OAR2: 118150665G>A, NC_019463.1 of genome assembly Oar_v3.1). (C) The F2 offspring resulting from outcrossing with the homozygous variant genotype (AA) for MSTN mutation (OAR2: 118150665G>A, NC_019463.1 of genome assembly Oar_v3.1). (D) The F2 offspring resulting from outcrossing with the homozygous variant (GG) genotype for Booroola/FecB mutation (OAR6: 29382188A>G, NC_019463.1 of genome assembly Oar_v3.1). (E) The BC1 offspring resulting from initial backcross generation.
