Final answer:
The study of Phylogenetics is true for comparing genomes and constructing evolutionary relationships among species. It uses both morphological and genetic evidence to build phylogenetic trees that trace the evolution of life.
Step-by-step explanation:
The level of inquiry in genetics that focuses on comparing the genome of different species, finding out the relatedness between different species, and constructing a tree of life is indeed called Phylogenetics. This is a true statement. Phylogenetics uses morphological and genetic evidence to deduce the evolutionary relationships among various species.
Homologous structures, which are features that overlap both morphologically and genetically, provide vital information for phylogenetic studies. For instance, the bones in the wings of bats and birds are examples of homologous structures that have evolved from a common ancestor.
Using tools like BLAST for comparative genomic approaches, scientists construct phylogenetic trees or cladograms to hypothesize the ancestral lineages and relationships. This is a significant aspect of evolutionary biology, as it helps in understanding the shared characteristics, evolutionary history, and potential genetic links that could further refine the understanding of an organism's phylogeny.
