Abstract/Description: | The present investigation was conducted to study the effect of sample size for estimating the precision of heritability by regression of the offspring on the parent and to decided the optimum number of bootstrap replications required for precision of heritability. This was achieved empirically by using the stimulated data for different value of population parameters. The bootstrap technique, which is an analytical and highly computer oriented method, was used to obtained from the data simulated by the parent –offspring model by selecting different master sample of 200,500,1000 and 1500 pairs of observations from the population with different heritability level for different bootstrap replication numbers. The optimum number of bootstrap replication required to obtain a stable estimate of standard errorof heritability for all the three cases considered about 100, except for small sample for which at least 200 bootstrap replication wee required. The optimum sample size required to get precise estimate of the standard error for both low and moderate heritability values was about 1000. But the sample size of 500 was sufficient for high heritability values. |
