Question

Explain what the genetic tree of the world’s populations is. What conclusions could be drawn from it?

Answer 1

Phylogenetic tree? It 's also called as evolutionary tree. It is a branching diagram of evolutionary Relationships among various living organisme This tree is drawn based on similarities and dis similarities in there physical on genetic characteristies: . If whole life on earth ęę Indicated by one phylogenetic tree, then all share a Common Ancestry.

Population populations Dopulation Genetics? w It deals with genetic differences within ulations of it is thus included in evolutionary biology. This field involves the study of each copulation and compairing them by examining bhenomena lile speciation, Natural selection, adaptation etc. ay It helps in studying the genetic diversity and population divergences - Genetic tree of World Populations It involves the representation of the World's population by means of their genes and their relationships in the form of al tree Most human population history can be revealed by this trees. → It includes population from different parts of the world but which are evolved from some Common ancestry. Howeves, human popielation history is certainly not purely tree-like as there involves many others like migration, Mutations, Selections, Recombinations , hierarchical signal, gene flow > In a Genetic tree of World Population of Humans the most basal position : - Occupied by Africal people

LEYTE → There include some stable, some unstable and even some wild taxa in a population and there are included in the genetic tree. ---- Austesalions - southeast Asian - Americans - Northeast Asian - Europeans - Non-European African tu smell population representation buy genette free Conclution f y Relationship between populations at different plances 'can be compared. The phenotypic and genotypic relationships of population can be studied. 7 The levels of Gene Variation and Gene study can be known easily. → The populalion history Berealed. 7 we can conclude that some populations are more selective than other The recombination f mutations can be studied. Gene distance between populations known
