Performance evaluation of bootstrap strategies on the estimate of standard error of heritability by half-sib method.

Abstract

The important genetic parameter, heritability indicates the relative importance of the genetic and environmental sources of variation in the character and is termed as degree of genetic determination of the character. Singh and Wahi (2003) obtained the optimum family size and structure for estimating the standard error of heritability in half-sib model. Singh et al. (2006) studied the robustness of bootstrap estimates of variance of heritability to master samples by drawing independent master samples in half-sib model. Keeping in view the importance of bootstrap technique the performance of different bootstrap strategies on estimate of the precision of heritability in half-sib model is investigated in depth.
