lineage -- Any continuous line of descent; any series of organisms connected by reproduction by parent of offspring.
lipids -- a class of biochemical compounds which includes fats, oils, and waxes.
Lineage
Main article: Stem cell line
To ensure self-renewal, stem cells undergo two types of cell division (see Stem cell division and differentiation diagram).
Lineage. A chart that traces the flow of genetic information from generation to generation.
Lineage
Linear evolutionary sequence from an ancestral species through all intermediates to a descendant species.
The lineage of animals which joins reptiles and mammals is often touted here as an excellent example of a transitional series.
Cell Lineage Mapping and C. Elegans
Drosophila melanogaster is not the only model organism for developmental genetic studies.
amniote lineage The evolutionary lineage of vertebrates leading to modern reptiles, birds, and mammals.
amniote Having an amnion; as a noun, an animal that develops an amnion in embryonic life, that is, reptiles, birds, and mammals.
Synonym: lineage, line, family, house, breed, offspring, progeny, issue.
Origin: F. Race; cf. Pr. & Sp. Raza, It. Razza; all from OHG. Reiza line, akin to E. Write. See Write.

The amniote lineage (the first truly terrestrial vertebrates that did not need to return to water to lay eggs), especially the fossils, often are classified based on the number of openings in the skulls.
clone
A lineage of genetically identical individuals.
closed circulatory system
A type of internal transport in which blood is confined to vessels.
A pure-breeding lineage, usually of haploid organisms, bacteria, or viruses.

Pedigree The lineage or record of ancestors of a germplasm.
PFAM Pfam is a database of multiple alignments of protein domains or conserved protein regions.
1-10 2 How transcriptional and epigenetic programmes are played out on an individual mammalian gene cluster during lineage commitment and differentiation Douglas R.
This reflects the very active duplication, divergence, and either functional or total loss of genes since separation of rodent and primate lineages.
The first reptiles (often referred to as the stem reptiles) gave rise to several other lineages, each of which adapted to a different way of life.
In most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route.
The ancestor of the first prokaryotic cells diverged into three lineages: the two main prokaryotic lineages are the eubacteria and the archaebacteria and the third was the prokaryotic ancestor of the present day eukaryotes.
A method to study cell lineage or function by selectively destroying a small number of cells. For example, a laser beam can be used to focus on and kill one cell in C. elegans.
Ablation experiment: An experiment designed to produce an animal deficient in one or a few cell types, in order to study cell lineage or cell function.
(1) A lineage of genetically identical individuals or cells. (2) In popular usage, a single individual organism that is genetically identical to another individual. (3) As a verb, to make one or more genetic replicas of an individual or cell.
- is made of cells derived from several different lineages. One might have expected that the earliest cell divisions would produce daughter cells destined to go on to form a single structure in the embryo. But that is not generally the case.
Convergent evolution: Evolution of two or more different lineages towards similar morphology due to similar adaptive pressures.
Evolutionary change producing a single lineage in which one taxon replaces another without branching.

Somatic cell A cell which is not on the lineage from which gametes are made. (see germline)
Somatic cell genetics The study of genes using hybrids (fusions) between the somatic cells of different species.
Population genetics looks at the level of an entire population, and systematics considers the multi-species scale of lineages. Interdependent populations and their habitats are examined in ecology and evolutionary biology.
