In Biology, a genus (plural: genera) is a low-level taxonomic rank used in the biological classification of living and fossil organisms, which is an example of definition by genus and differentia. Genera and higher taxonomic levels such as families are used in biodiversity studies, particularly in fossil studies since species cannot always be confidently identified and genera and families typically have longer stratigraphic ranges than species.[1]
The term comes from Latin genus "descent, family, type, gender",[2] cognate with Greek: γÎνος -- genos, "race, stock, kin".[3] The hierarchy of biological classification's eight major taxonomic ranks. A family contains one or more genera. Intermediate minor rankings are not shown.
The composition of a genus is determined by a taxonomist. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. In the hierarchy of the binomial classification system, genus comes above species and below family.
ContentsSpecies. Explanation : Let us consider the next level of classification which is Genus. Genus is a group of closely related species. So, there are more number of organisms here as there are more than one specie. The next level is Family which is a group of closely related genera (Plural of genus). Now, here, there many genera which in turn contains many species. The levels of classification are such that each level contains more number of organisms than the previous level. So, it is called a Hierarchy of classification.
An example of a mineral that contains more than one element is feldspar, which is a group of rock-forming tectosilicate minerals. Feldspar typically contains a combination of elements such as aluminum, silicon, oxygen, potassium, calcium, and sodium in varying proportions.
Haploid
No, each flower on an almond tree produces about 2 almonds each. So pretty close to the #1, but produces 1 more almond each.
Each sex cell now contains one allele for each trait. This is because sex cells are haploid, meaning they only contain one set of chromosomes with one allele for each gene. During fertilization, two sex cells will combine to form a diploid zygote with two alleles for each trait.
genera
i think its species
There are 79 species of hagfish that are split up into six different genus. The genus Eptatretus contains 49 species, the genus Myxine contains 23 species, the genus Nemamyxine contains two species, the genus Neomyxine contains one species, the genus Notomyxine contains one species, and the genus Rubicundus contains four species.
- a domain is the highest level of organization - within a domain, there are kingdoms - withing kingdoms, there are phyla (singular phylum) - within phyla are classes - within classes are orders - within orders are families - each family contains one or more genera - each genus contains one or more species
A monotypic genus contains only one species.

1) A domain is the highest level of organizations. 2) Within a domain there are kingdoms. 3) Within kingdoms there are phyla. 4) within phyla there are classes. 5) Within classes are orders. 6) With in orders are families. 7) Each family contains one or more genera. 8) Each genus contains one or more species.
Species. Explanation : Let us consider the next level of classification which is Genus. Genus is a group of closely related species. So, there are more number of organisms here as there are more than one specie. The next level is Family which is a group of closely related genera (Plural of genus). Now, here, there many genera which in turn contains many species. The levels of classification are such that each level contains more number of organisms than the previous level. So, it is called a Hierarchy of classification.
The largest living mammal is the blue whale, which is also the largest animal that has ever lived. It is in the genus Balaenoptera, but the genus also contains some whales that are smaller than some other whales of other genera (plural of genus). Thus, the genus itself is not the largest of living mammals, but one species that it contains is.
A genus is a taxonomic rank that includes one or more species that are closely related. It represents a group of species that share common characteristics and ancestry. Genera are further organized into families, then orders, classes, phyla, and ultimately kingdoms in the classification system.
be more similar to each other than they are to other species
The second part of the scientific name, known as the specific epithet, is unique to each species within a genus. It helps to distinguish one species from another within the same genus and is specific to that particular organism.
