The extensive clustering of cancer cases within members of family 41 is of particular interest, since thirteen family members spread across three successive generations were diagnosed with five different cancer types.
Moreover, while the genetic trends across four successive generations showed that growth rate increased across generations by selection, no correlated genetic change in uniformity of growth rate was found during the same period, when uniformity was estimated based on log-transformed data (residual variation scaled by the trait mean).
Approximately half of CRC cases who meet AC1 (three relatives with CRC across two successive generations (with one case being a first-degree relative of the other two), at least one case diagnosed before age 50, and the exclusion of familial adenomatous polyposis), are now classified as FCCTX (Lynch & de la Chapelle, 2003; Renkonen et al, 2003; Schiemann et al, 2004; Woods et al, 2005).
Plants were then backcrossed with Ningyou7 over five successive generations (BC1 to BC5).
The heterozygotes of OsRDR1 were selfed for five successive generations, and in each of the first four generation (S1-S4) only heterozygous individuals were selected based on PCR identification.
The Varian ranch now has bred nine generations of horses descended from these foundation mares, and has stood five successive generations of stallions descended from Bay Abi.
In particular, BC1 populations are generated from crosses in two successive generations.
The seeds were derived from a single plant propagated from single seeds over eight successive generations.
However, a developmental reversion of these modifications may be observed throughout two successive generations.
I'm the only person I know whose family history involves the triple-whammy of three successive generations of divorce.
For individuals born between 1740 and 1968 we have reconstructed the genealogies for three successive generations using the data based on the parish registers.
