Explain why genetic analysis provides the most definitive indicator of relatedness among organism

A genetic analysis is a test that aims to analyze DNA, that is, the chemical database that contains the information of the organism.The analysis of various genetic markers in the organisms studied allows to establish a paternal-filial relationship or determine if it exists some kind of shared biological ancestry

Explanation:

To carry out a genetic study, we must study the genetic material stored in our cells. A genetic study is one that includes “the study of DNA, RNA, chromosomes, proteins and certain metabolites, in order to detect genotypes, mutations, phenotypes or karyotypes. All biological kinship tests are based on obtaining and analyzing the genetic material (DNA) of the organisms to be analyzed to study their genetic markers and compare them in each organism.Genetic markers are segments of DNA located at a known position (a locus) on a certain chromosome. Genetic markers are randomly received from biological parents following the rules of simple Mendelian inheritance. The presence of a pattern of genetic markers (called alleles) different from those of their parents would indicate that they are not their biological parents. Analyzing a sufficiently high number of markers could reach a point where, using specific statistical procedures, the studied relatedness link can be confirmed or discarded.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
