Asexual organisms can have homologous chromosomes, particularly if they are diploid, meaning they have two sets of chromosomes—one from each parent. In such organisms, homologous chromosomes carry the same genes, though they may have different alleles. Asexual reproduction, such as binary fission or budding, typically involves the replication of genetic material before cell division, but the presence of homologous chromosomes is dependent on the organism's genetic structure. In contrast, haploid organisms, which have only one set of chromosomes, do not possess homologous chromosomes.
If the body cells in an organism have no homologous pairs of chromosomes, the organism is most likely to be haploid. This condition is typical of organisms that reproduce through asexual means or certain stages in the life cycle of gametes in sexually reproducing organisms. Examples include many fungi and some algae. In such cases, the cells contain a single set of chromosomes rather than pairs.
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
The term that describes chromosomes existing as homologous pairs is "diploid." In diploid organisms, each chromosome has a corresponding homologous chromosome inherited from each parent, resulting in pairs of similar chromosomes. This configuration is crucial for processes like meiosis, where genetic diversity is generated through recombination and segregation of these homologous chromosomes.
The karyotype of the asexual organism would not contain homologous chromosomes

Homologous chromosomes
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
Chromosomes that contain genes for the same characteristics are called homologous chromosomes. They carry similar genetic information, one inherited from each parent, and play a key role in genetic inheritance and variation. During meiosis, homologous chromosomes undergo recombination, contributing to genetic diversity.
