1. Effect of other possible characters towards dependent characters which are not included in the study is known as
(i) Direct effect
(ii) Indirect effect
(iii) Residual effect
(iv) Casual effect
2. Choose the incorrect statement
(i) Path analysis is based on all possible simple correlations among various characters
(ii) Representation of the direct and indirect effects of a set of independent variables on the dependent variable in the form of a diagram is known as path diagram
(iii) A line diagram which is constructed with the help of simple correlation coefficients among various characters under study is called as cluster diagram
(iv) Indirect effects can be computed by using the values of correlation coefficients and direct effects
3. In plant breeding phenotypic and genotypic path are commonly used to determine
(i) Yield contributing characters
(ii) Selection of elite genotypes from diverse genetic population
(iii) Both (i) and (ii)
(iv) None of these
4. Phenotypic, genotypic and environmental path are estimated from
(i) Replicated data only
(ii) Unreplicated data only
(iii) Both (i) and (ii)
(iv) None of these
5. If the correlation coefficient between a casual factor (character that causes the effect) and the effect is equal to its direct effect, then it denotes
(i) The indirect effect is due to correlations
(ii) Restriction to be imposed to nullify the undesirable indirect effects in order to make use of direct effects
(iii) True relationship and direct selection should be rewarding
(iv) Indirect selection is done for achieve greater yield response
