A fungus contains cells with two nuclei from different genomes. The nuclei do not fuse but divide independently and simultaneously as new cells are formed. It belongs to

Options

A. Phycomycetes
B. Zygomycetes
C. Deuteromycetes
D. Basidiomycetes

Answer

To solve the question regarding the type of fungus that contains cells with two nuclei from different genomes, we will follow these steps:

### Step 1: Understand the Characteristics of the Fungus
The fungus in question has cells with two nuclei that do not fuse but divide independently and simultaneously. This indicates a unique reproductive or cellular structure.

### Step 2: Identify the Type of Hyphae
The transcript mentions two types of hyphae: primary hyphae and secondary hyphae. Primary hyphae are haploid (n), while secondary hyphae are diploid (2n). The presence of two nuclei suggests that the organism undergoes a specific type of reproduction.

### Step 3: Recognize the Process of Nuclei Division
The nuclei in the fungus do not fuse, which is a key characteristic of certain fungal groups. Instead, they divide independently, which is typical for fungi that reproduce sexually.

### Step 4: Determine the Fungal Group
The transcript indicates that this characteristic is exclusive to the group of Basidiomycetes. This group of fungi is known for having a dikaryotic stage (where cells contain two nuclei) that does not involve the fusion of nuclei.

### Step 5: Conclude the Answer
Based on the characteristics described, the correct classification of the fungus is Basidiomycetes.

### Final Answer
The fungus belongs to the group of **Basidiomycetes**.
