(a) Effect of radiation on living organisms
(b) Biochemical explanation of genetic phenomena
(c) Effect of environment of genetic set up of organisms
(d) Inheritance of quantitative traits

Options

A. Effect of radition on living organisms
B. Biochemical explanation of genetic phenomena
C. Effect of environment of genetic set up of organisms
D. Inheritance of quantitative traits.

Answer

To solve the question regarding biometric genetics, we need to analyze what biometric genetics specifically deals with. Here’s a step-by-step breakdown:

### Step 1: Understand Biometric Genetics
Biometric genetics is a branch of genetics that focuses on the statistical analysis of biological data. It primarily deals with the inheritance of quantitative traits, which are traits that can be measured and are typically influenced by multiple genes and environmental factors.

**Hint:** Think about what biometric genetics measures and analyzes.

### Step 2: Evaluate Each Option
Now, let's evaluate each of the provided options to see which one aligns with the definition of biometric genetics.

- **(a) Effect of radiation on living organisms:** This option refers to the study of how radiation affects biological systems and is not related to the statistical analysis of genetic traits. Thus, it is not connected to biometric genetics.

- **(b) Biochemical explanation of genetic phenomena:** This option deals with the biochemical processes underlying genetics, which is more molecular biology than biometric genetics. Therefore, it is not the correct answer.

- **(c) Effect of environment on genetic setup of organisms:** While the environment can influence genetic traits, this option does not specifically relate to the statistical analysis of those traits, which is the focus of biometric genetics.

- **(d) Inheritance of quantitative traits:** This option directly relates to the core of biometric genetics, which studies how quantitative traits are inherited and the statistical methods used to analyze these traits.

**Hint:** Focus on which option directly relates to the statistical analysis of traits and their inheritance.

### Step 3: Conclusion
After evaluating all the options, it is clear that the correct answer is **(d) Inheritance of quantitative traits**. This option best describes the primary focus of biometric genetics.

**Final Answer:** (d) Inheritance of quantitative traits.
