Answer:
Presence of descendants of most recent ancestor in organism group decides that certain species falls under monophyletic or paraphyletic.
Explanation:
Monophyletic : Monophyletic taxon or Clade Monophyletic is named to group composed of collection of organisms that includes most recent common ancestor of all those organism and all descendants of most recent common ancestor
Paraphyletic : Paraphyletic taxon or is named to group composed of organisms having most recent common ancestor of organisms. This is different from Clade Monophyletic as it does not include all descendants of most recent common ancestor.
Examples for Clade Monophyletic are: Insects, Aves (Birds) etc.
Examples for Paraphyletic : Invertebrates, Fish etc.
In Meiosis, Anaphase 1 consists of the separation of homologous chromosomes. However, anaphase 2 consists of the seperate of sister chromatids.
