the part grows at the same rate as the body as a whole, and when b [not equal to] 1, the growth is heterogonic, i.
0 mm of fat thickness showed positive heterogonic development.
0 mm fat thickness had a positive heterogonic growth (b > 1), since it is known that the fat tissue has a late growth.
Total fat only had a positive heterogonic growth in the treatment 3.
With longer time of confinement, bone tissue had its heterogonic positive growth compared with the growth rate of the carcass.
Growth was considered to be heterogonic for b [not equal to] 1 and was positive for b > 1 and negative for b < 1.
Male lamb from all of the genetic groups and females from the Ile de France x Santa Ines and Bergamasca x Santa Ines crosses presented allometric coefficients of less than 1 for the feet/ankles (Table 1), corresponding to negative heterogonic growth.
Except to Bergamasca x Santa Ines females, the allometric coefficients for the heads were less than one (Table 2), indicating negative heterogonic growth, as the head grew faster than the empty body.
Bergamasca x Santa Ines males exhibited a skin allometric coefficient greater than one (Table 1), indicative of positive heterogonic growth; i.
Many monogonont rotifers have heterogonic
life cycles (Gilbert 1980, 1983, 1992, 1993).
Artificial selection for heterogonic development is highly successful (Viney 1996) which, together with population differences in the occurrence of sexual morphs, provides good evidence of the "balance" argument: in natural populations, natural selection must be maintaining the sexual cycle (Williams 1975).
This has led to the general conclusion that heterogonic development occurs when conditions outside the host are favorable and those inside are unfavorable (Moncol and Triantaphyllou 1978; Schad 1989).
