Where owls had bred, the average number of offspring was only two rather than the four or five required for population recovery.
Monitoring of sites has revealed where birds have managed to breed, and the average number of owlets at each site is just two, compared with the four or five needed for population recovery.
Thus, in the first group of breeds the average frequencies of the I-668 and G-660 alleles were 0.08 and 0.61, respectively.
For subspecies/groups such as the Taurine, Indicine, Composite (Taurine × Indicine) and African breeds, the average CNV events per sample were 45, 65, 53 and 66 respectively (i.e. T I C A = 45:65:53:66).
The proportional contribution of each breed to the average heterozygosity of the metapopulation, resulted in many negative values (10 breeds), which, if these breeds were removed, would lead to a 'gain' in diversity.
To estimate the relative diversity among animals in breed groups, the average relationships were computed with CFC version 1.0 (Coancestry, Inbreeding (F), Contribution) [ 29].
We next performed a quantitative association with body mass using all 46 breeds, using the breed average values for sex-averaged mass in kg (Table 1).
These jobs breed loyalty: Average tenure is 25 years, and the turnover rate is a low 4%.
The 30 males also started to breed on average of 3 days earlier in 2004 than in 2003, but this difference was not statistically significant (Table 3).
He runs a flock of 1,000 Ţurcana ewes and rams which breed, on average, 500 lambs once a year.
