A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae , but that family is commonly referred to as the "walnut family".

Each family's formal name ends in the Latin suffix -aceae and is derived from the name of a genus that is or once was part of the family. [3] The table below contains seed-bearing families from Plants of the World by Maarten J. M. Christenhusz (lead author), Michael F. Fay and Mark W. Chase, with two updated families [a] from Plants of the ...
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.
Family tree showing the relationship of each person to the orange person, including cousins and gene share. A family tree, also called a genealogy or a pedigree chart, is a chart representing family relationships in a conventional tree structure. More detailed family trees, used in medicine and social work, are known as genograms.
Phylogenetic tree of the Mup gene family. A gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions. One such family are the genes for human hemoglobin subunits; the ten genes are in two clusters on different chromosomes, called the α-globin and β-globin loci
Family (from Latin: familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). It forms the basis for social order. [1] Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. [2]
To research the developmental biology of the bird embryo, researchers produced artificial quail-chick chimeras in 1987. By using transplantation and ablation in the chick embryo stage, the neural tube and the neural crest cells of the chick were ablated, and replaced with the same parts from a quail. [ 53 ]
