MCQ on Biometrical Genetics / Quantitative Genetics Part -29 For ARS NET / SRF Exams

 

1. Choose the incorrect statement

(i) A character showing positive direct effect on yield may have a negative indirect effect via other component traits

(ii) If residual effects are high, it means beside the characters studied, there are some other attributing characters that influence yield

(iii) Path analysis is also known as cause and effect relationship

(iv) Path analysis provides information about only indirect effects of traits on yield

2. Choose the correct statement

(i) A table, which depicts as possible as direct effects and indirect effects is called as path table

(ii) Path analysis is based on assumption of linearity and additivity

(iii) In plant breeding path analysis is done for determining yield components

(iv) All of these

3. Path analysis estimates

(i) Direct effects

(ii) Indirect effects

(iii) Residual effects

(iv) All of these

4. Choose the correct statement

(i) Path diagram is constructed by using the all possible value of simple correlations

(ii) Statistical techniques that splits the correlation coefficient into the measure of direct and indirect effects is called as path analysis

(iii) Path diagram is constructed by using the all possible value of simple correlations

(iv) All of these
