zygo-, zyg-, -zygous; zygomatico- +

(Greek: yoke, forming pairs; joined, union; or indicating a relationship to a junction; meaning a yoke or crossbar by which two draft animals; such as, oxen could be hitched to a plow or wagon)

zygomycosis
A dangerous infection caused by a water-borne fungus.

Zygomycosis is seen most often in patients who are already ill with diseases that cause wasting; such as, AIDS or poorly controlled diabetes.

If unchecked, the fungal infection can spread to the lungs and other organs, the blood, the eyes, and the brain. Treatment is two-fold: controlling the underlying condition, and attacking the infection with anti-fungal medications.

zygon
The short crossbar connecting the branches of a zygal fissure which is a figure formed by two nearly parallel cerebral fissure's (long narrow openings) connected by a short fissure (groove) at right angles, forming an H.
zygoneure
A nerve cell which interconnects with other neurons.
zygophyllaceous
Flowering plants that have pinnate leaves (a central stem with parts branching off it like feathers) and capsules as fruits.
zygophyte
A plant in which reproduction is done by the union of two similar reproductive cells which unite in fertilization.
zygopodium
The distal intermediate segment of the limb of the skeleton; that is, radius and ulna (two of the large bones of the forearm), tibia (shinbone) and fibula (outer and thinner of the two bones of the human leg between the knee and the ankle).
zygose
A descriptive term for the union or conjugation of two gametes (mature sexual reproductive cells; such as, sperms or eggs, that unite with other cells to form new organisms.
zygosis
1. A form of sexual reproduction in unicellular organisms, consisting of the union of the two cells and a fusion of their nuclei.
2. The fusion or union of the nuclei of a male and a female gamete (a cell whose nucleus unites with that of another cell to form a new organism) in algae and fungi.
zygospore
A large multinucleate spore formed by union with similar gametes, as in algae or fungi.
zygostyle
The most inferior coccygeal vertebra or the small tail-like bone at the bottom of the spine near the anus, which consists of up of 3-5 (average of 4) rudimentary vertebrae or the thirty-three bony segments that form the spinal columns of humans.
zygotaxis
Mutual attraction between male and female gametes.
zygote
The cell formed by the union of a male sex cell (a sperm) and a female sex cell (an ovum).

The zygote develops into the embryo following the instruction encoded in its genetic material, the DNA.

The unification of a sperm and an ovum to form a zygote constitutes fertilization.

zygotic
A reference to an organism which develops from a zygote or a single cell (fertilized ovum) that contains the genetic material of both the female and the male.
zygotic lethal gene
A gene which allows the normal functioning of gametes (reproductive cells in animals and plants), but has lethal (deadly) effects during embryonic or larval development.
