Question

How are the groupings of morphological phylogeny different or similar to molecular phylogeny?

Answer 1

Difference between morphological and molecular phylogeny Molecular Phylogen It focuses on the similarity of the DNA Morphologic It focuses on the similarity of the anatomical featuresi.e., species that are sequences (genomics) or the expression more closely related have much similar anatomical features and have branched off most recently en products such as proteins (proteomics) For example, It divides the bilaterians into two clades: deuterostomes and protostomes Clades into three groups: Deuterostomia, while within the protostomes, arthropods are grouped with annelids because both groups It also shows arthropods and annelids are have segmented bodies Much more applicability for the specimens of the main advantage associated wit which are preserved or frozen comparedto molecular phylogenetics is the extent of data molecular phylogenetics To reveal the morphological variation in fossils information from living species is However, molecular phylogeny divides and Ecdysozoa. not closely related set with is limited to the nucleotide sequences of the organism. The already known sequences of the explored organism are available in the data bases and newly evolving groups are compared with various bioinformatics tools to develop a molecular phylogenetic relationships Mitochondrial DNA and ribosomal RNA genes are used to form such relationships Nonheritable variations problems confo eeded and this can be traced with morphological phylogeny compared to molecular phylogeny Studies anatomical features Nonheritable variations affect morphologi analysis compared to molecular phylogenyin morphological analysis are solved in the molecular phylogen more affected by environmental influences Less affected by environmental influences compared to molecular phylogen compared to morphological phylogen
