backcross
retrocroisement m

Retrograde chiasm. Genetic crossover in which heterozygous parents intersect with homozygous parents. Thus, it is possible for two cross-references to occur. For example: In the case of the fruit fly Drosophila, the normal vestigial wing is dominant over the dominant wing, and thus heterozygous flies have normal wings.
The figure below shows the two retrograde chiasms.

Recessive cross-crossing is useful in distinguishing between organisms with the same phenotype and different genotypes. For example: 77 and 77 (this cross is called a test cross).

Germs. Unicellular organoids with a diameter of 1-2 micrometers. Some germs cause disease, such as tetanus, but others are useful as a source of antibiotics, for example.

balanced diet

A balanced diet, a synthetic diet

A balanced diet with the correct nutritional components needed for health, generally used in reference to humans and pets. A balanced human diet should contain:

(1) Sufficient energy, measured in kilojoules.
(2) protein
(3) Carbohydrates
(4) fat
(5) Vitamins
(6) Water
(7) Mineral salts
(8) roughage

basal metabolic rate (BMR)

They are also physically fit

Basal metabolic rate. An animal's metabolic rate at rest, as measured by oxygen consumption. The basal metabolic rate is the minimum amount of energy needed to maintain life, and it varies depending on the species, age, and gender.

bile
bile f

Bile is a green, alkaline liquid secreted by the liver in mammals. Bile is stored in the gallbladder and transported through the bile duct to the duodenum, where it breaks down fat into fine droplets (emulsification) before digestion. See digestion and duodenum.

binary fission
fission f binaire

Asexual reproduction of unicellular organisms in which a cell divides to produce two cells.

The cell nucleus divides by mitosis. Binary fission is common in bacteria and protozoa, such as amoeba, where a mother cell divides into two completely identical daughter cells.

Two daughter cells

binomial nomenclature
nomenclature fbinomiale

Linnaeus system. Double label. Naming method
The organisms developed by Carl Von Line (Linnaeus) in the eighteenth century, where each organism is given two Latin names, the first beginning with a capital letter and indicating the genus, and the second beginning with a lowercase letter and indicating the species. For example:

Common name: domestic dog
Species (family) familiaris
Genus (dog) Canis

Common name: American wolf
Type (wolf) lupus
Genus (dog) Canis
