Molecular phylogenetics (/ məˈlɛkjʊlər ˌfaɪloʊdʒəˈnɛtɪks, mɒ -, moʊ -/ [1][2]) is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which ...
Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...
molecular genetics A branch of genetics that employs methods and techniques of [[Glossary of genetics (M–Z)molecular biology#{{{1}}}| {{{1}}}]] to study the structure and function of genes and gene products at the molecular level. Contrast classical genetics. monophyly morphological species concept mosaic evolution
Morphogenesis. Morphogenesis (from the Greek morphê shape and genesis creation, literally "the generation of form") is the biological process that causes a cell, tissue or organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of tissue growth and patterning of cellular ...
Neuromorphology. Neuromorphology (from Greek νεῦρον, neuron, "nerve"; μορφή, morphé, "form"; -λογία, -logia, “study of” [1][2]) is the study of nervous system form, shape, and structure. The study involves looking at a particular part of the nervous system from a molecular and cellular level and connecting it to a ...
A continuous morphological variation in form within a species or sometimes between two species. clone A plant derived from the asexual vegetative reproduction of a parent plant, with both plants having identical genetic compositions. coalescent Having plant parts fused or grown together to form a single unit. cochleariform Concave and spoon-shaped.
e. Molecular biology / məˈlɛkjʊlər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. [1][2][3] Though cells and other microscopic structures had been observed in living organisms as early as the ...
The characteristics used to create a cladogram can be roughly categorized as either morphological (synapsid skull, warm blooded, notochord, unicellular, etc.) or molecular (DNA, RNA, or other genetic information). [7] Prior to the advent of DNA sequencing, cladistic analysis primarily used morphological data.
