The Effect of Inbreeding on Reproductive Fitness of S. C. W. Leghorns

摘要: Abstract THE reproductive fitness of an animal may be defined as the number its offspring reaching breeding age. When all birds in a flock are given equal opportunity to reproduce themselves, sense that beginning and duration hatching season held constant no young culled, wide variation exists. This is particular importance production inbred lines, where selection for have practiced order prevent rates from decreasing below replacement levels. Should dependent on degree homozygosity either parents or (thus producing differential elimination), accuracy computed increases under inbreeding (the coefficients) brought into question. The present study designed throw some light this question, .
