Model organism are non-human species that are used in the laboratory to help scientists understand biological processes. There are usually organisms that are easy to maintain and breed in a laboratory setting.
Comparative genomics is used to study similarities and differences in the genomes of different species. It can help researchers understand evolutionary relationships, identify genes responsible for specific traits, and provide insights into genetic variations that contribute to diseases. Comparing genomes can also aid in the discovery of new genes and regulatory elements.
Pseudogenes are non-functional copies of genes that have accumulated mutations over time. By comparing pseudogenes across different species, scientists can study genetic changes that have occurred during evolution. Pseudogenes provide valuable insights into evolutionary processes and relationships between species.
In genetic epidemiology, a genome-wide association study(GWA study, or GWAS), also known as whole genome association study (WGA study, or WGAS), is an examination of all or most of the genes (the genome) of different individuals of a particular species to see how much the genes vary from individual to individual. Different variations are then associated with different traits, such as diseases. In humans, this technique has led to discovery of associations of particular genes with diseases such as the eye disease known as age-related macular degeneration and diabetes. In humans, hundreds or thousands of individuals are tested, usually for single DNA mutations (single-nucleotide polymorphisms, or SNPs). As of December 2010[update], over 1,200 human GWASs have examined over 200 diseases and traits, and found almost 4,000 SNP associations.[1] They are useful in finding the molecular pathways of disease, but usually not useful in finding genes that predict risks of disease
to study genetic variation within a species or a populationto identify genes that are important for evolution of a particular speciesto study how genomes evolveto identify homologues in model organisms for genes involved in human diseaseAll of the above are goals of comparative genomic studies.
Genetics is the science that studies how traits are inherited through the interactions of genes, which are segments of DNA that code for specific traits. It examines how genetic information is passed down from one generation to the next and how variations in genes can lead to different traits in individuals.
the answer i believe is orthologous genes because they homologous genes in species.

DNA sequencing would be the most useful molecular analysis in deciding the exact classification of similar species. By comparing the nucleotide sequences of specific genes or regions of the genome, scientists can identify genetic differences that can help distinguish between species that are otherwise very similar morphologically or ecologically. DNA sequencing provides a high level of accuracy in determining species classification and can help resolve taxonomic confusion.

A quadrat is a small plot that is used in ecology that isolates an area for study. It is useful for studying insects by helping to measure the percentage cover for insect species.
