Give an account of the common modifications of mitosis.

Answer

### Step-by-Step Text Solution:

1. **Introduction to Mitosis Modifications**:
Mitosis is a fundamental process of cell division that results in two daughter cells with identical genetic material. However, there are common modifications of mitosis that can lead to variations in the process.

2. **Alterations in Chromosomes**:
One of the primary modifications in mitosis involves alterations in the chromosomes. These alterations can result in changes in the genetic makeup of the daughter cells, potentially leading to the emergence of new species or traits.

3. **Segregation of Chromosomes**:
The segregation of chromosomes during mitosis is another area where modifications can occur. The percentage of segregation is influenced by the linkage of genes on the chromosomes. This means that how genes are arranged and inherited can affect the outcome of mitosis.

4. **Integration of Chromosomal Relationships**:
The relationships between chromosomes can be integrated in various ways during mitosis. This integration can lead to different genetic combinations in the daughter cells, contributing to genetic diversity.

5. **Outcome of Modifications**:
The modifications in mitosis can lead to the generation of new species or new characters. This is significant in evolutionary biology, as it highlights how mitotic variations can contribute to the diversity of life.

6. **Conclusion**:
In summary, common modifications of mitosis include alterations in chromosomes, variations in segregation percentages, and the integration of chromosomal relationships, all of which can result in new genetic traits or species.
