Explanation: for  moderator

This simply refers to the differences between the anaphase stage of Mitosis  and Meiosis.

At Anaphase  of Mitosis,there is centromere division.Therefore the homologous chromosomes separated into sister chromatids at the centromere, with each migrating to opposite poles of the cells.

At  Anaphase i of meiosis, there is no centromere division. Homologous chromosomes migrates together to opposite  poles lead by centromere.

At Anaphase ii, the homologous chromosomes undergo centromere division into sister chromatids, each migrating to opposite poles, thus behaving independently of one another.

thus Anaphase ii and anaphase of mitosis are the same.(children-Filho sister chromatids, but at Anaphase i, they are  homologous since no centromere division..

Explanation for the student in Portuguese

so se refere simplesmente às diferenças entre o estágio anafásico da mitose e da meiose.

Na Anáfase da Mitose, há divisão centrômero. Portanto, os cromossomos homólogos se separam em cromátides irmãs no centrômero, cada um migrando para pólos opostos das células.

Na Anáfase i da meiose, não há divisão centrômero. Os cromossomos homólogos migram juntos para os pólos opostos liderados pelo centrômero.

Na Anáfase ii, os cromossomos homólogos passam pela divisão do centrômero em cromátides irmãs, cada uma migrando para pólos opostos, comportando-se independentemente um do outro.

portanto, a anáfase ii e a anáfase da mitose são as mesmas (cromátides irmãs filhos-filho )mas na anáfase i, elas são homólogas, pois não há divisão do centrômero.

this species has a relatively low level of genetic

variation because the population was reduced to a small size approxi-

mately 10,000 to 12,000 years ago.

until   now,   we   have   primarily   focused   our   attention   on   genes  

within   individuals   and   their   related   family   members.   in   this  

chapter   and   chapters   25   and   26   ,   we   turn   to   the   study   of   genes   in  

a   population   or   species.   the   field   of

population   genetics

  is   con-

cerned   with   changes   in   genetic   variation   within   a   group   of   indi-

viduals   over   time.   population   geneticists   want   to   know   the   extent  

of   genetic   variation   within   populations,   why   it   exists,   and   how   it  

changes   over   the   course   of   many   generations.   the   field   of   popu-

lation   genetics   emerged   as   a   branch   of   genetics   in   the   1920s   and  

1930s.   its   mathematical   foundations   were   developed   by   theoreti-

cians   who   extended   the   principles   of   gregor   mendel   and   charles  

darwin   by   deriving   formulas   to   explain   the   occurrence   of   geno-

types   within   populations.   these   foundations   can   be   largely   attrib-

uted to three scientists: sir ronald fisher, sewall wright, and j. b. s.

haldane.   as   we   will   see,   support   for   their   mathematical   theories  

was provided by several researchers who analyzed the genetic com-

position   of   natural   and   experimental   populations.   more   recently,  

population   geneticists   have   used   techniques   to   probe   genetic  

variation   at   the   molecular   level.   in   addition,   staggering   advances  

in   computer   technology   have   aided   population   geneticists   in   the  

analysis   of   their   genetic   theories   and   data.   in   this   chapter,   we   will  

explore   the   genetic   variation   that   occurs   in   populations   and   con-

sider   the   reasons   why   the   genetic   composition   of   populations   may  

change over the course of several generations
