aThe specific mutations in a progeny could occur during meiosis or mitosis related specifically to this progeny.
bThe proportion represents “premeiotic mutations that get transmitted/number of total mutations in progeny, Nt/No.”
cThese three individuals are supposed to be progeny from outcrossing with another P. mira tree. In those cases, it is difficult to identify the de novo specific mutations because of the pollen derived from different trees. However, the inherited mitotic mutations are easy to identify.
dThis sample is a putative inner cross between branches B2 and B5, and the other 10 plants are self-pollinated products. In those genomes, it is easy to identify both the inherited somatic mutations and the de novo specific mutations in each progeny.
