Inbreeding and Inbreeding Depression on Body Weight in Iranian Shal Sheep
The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...
متن کاملInbreeding and inbreeding depression in endangered red wolves (Canis rufus).
In natural populations, the expression and severity of inbreeding depression can vary widely across taxa. Describing processes that influence the extent of inbreeding and inbreeding depression aid in our understanding of the evolutionary history of mating systems such as cooperative breeding and nonrandom mate selection. Such findings also help shape wildlife conservation theory because inbreed...
متن کاملAncestral inbreeding only minimally affects inbreeding depression in mammalian populations.
Inbreeding depression can be reduced, or purged, by selection against deleterious alleles. This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few. In this study I present and use two different regression mode...
متن کاملInbreeding Levels and Inbreeding Depression in a Farmed
A farmed population of rainbow trout under selection for over six generations from the Norwegian Salmon Breeding Company, Ltd. was investigated for levels of inbreeding and occurrence of inbreeding depression for body weight. The average percent inbreeding levels and percent of individuals with inbreeding greater than zero (in parenthesis) were 2.9 (59.3), 2.8 (49.8), 8.5 (87.1), 8.0 (82.8) and...
متن کاملInbreeding depression in Japanese quail.
usefulness of Japanese quail (Coturnix coturnix japonica) as an expenT z n t a l animal was first pointed out about eight years ago (WILSON, ABBOTT and ABPLANALP 1959, 1961; PADGETT and IVEY 1959). These birds have steadily gained in popularity since then, but few quantitative genetic studies have been reported to date. The present investigation was designed to assess the response of Japanese q...
