Who is considered as "father of actinobiology"?

Options

A. H.J. Muller
B. C. Auerbach
C. T.H. Morgan
D. G.J. Mendel

Answer

To determine who is considered the "father of actinobiology," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Actinobiology**:
- Actinobiology is a branch of biology that studies the effects of radiation on living organisms. It involves experimenting with different types of radiation to understand their impacts.

2. **Identify Key Figures in Actinobiology**:
- The transcript mentions several scientists and their contributions to the field of biology, particularly focusing on radiation and its effects.

3. **Focus on H. J. Muller**:
- The transcript specifically states that H. J. Muller is recognized for his pioneering work in actinobiology, particularly in 1923. His research laid the groundwork for understanding how radiation affects living organisms.

4. **Consider Other Scientists Mentioned**:
- While C. Orbach, T. H. Morgan, and G.J. Mendel are notable figures in their respective fields, their contributions do not pertain directly to actinobiology.
- C. Orbach focused on mutagenesis, T. H. Morgan on genetics, and G.J. Mendel on heredity.

5. **Conclude the Answer**:
- Based on the information provided, H. J. Muller is the correct answer as he is considered the "father of actinobiology."

### Final Answer:
H. J. Muller is considered the "father of actinobiology."
