The joining of an egg and sperm at conception to create an embryo.
The union of the male gamete or sperm and the female gamete or egg and of their nuclei to form a zygote.
Fertilisation occurs when a sperm penetrates an egg. The moment when a sperm fertilises an egg is also called conception, and conception usually takes place in one of the Fallopian tubes.
when sperm enters an egg during sex and forms a new cell which eventually becomes a foetus.
The penetration of an egg by a sperm.
The union of two different types of gametes to form a zygote.
The penetration of the egg by the sperm and the resulting fusion of genetic material that develops into an embryo.
Sperm penetrating the egg which can lead to pregnancy.
The fusion of a sperm with an ovum, normally in the outer end of the fallopian tube.
Occurs when an egg and sperm meet successfully to form an embryo.
the penetration of the egg by the sperm that results in an embryo.
fert-ill-eyes- ay-shun Joining of a male sex cell (gamete) with a female sex cell (gamete)
The process in which a sperm enters an egg and triggers further development. We say fertilisation has occurred when we see the nucleus of the sperm together with the egg nucleus inside the egg cell under the microscope.
Penetration of the egg by the sperm and joining of genetic materials to result in the development of an embryo.
Conception. When the egg cell meets the sperm cell.
The penetration of the egg by the sperm to create a zygote
Union of a sperm and egg to form a new being (zygote, conceptus etc)
Conception or fertilisation is the moment when sperm and egg meet, join and form a single cell. It usually takes place in the Fallopian tubes. The fertilised egg then travels into the uterus, where it implants in the lining before developing into an embryo and then a fetus.
the process whereby male and female gametes unite, beginning when a sperm contacts the outside of the egg and ending with the formation of the zygote.
the process by which a sperm unites with an egg
The combining of the genetic material carried by sperm and egg to create an embryo. Normally occurs inside the fallopian tube (in vivo) but may also occur in a petri dish (in vitro). See also In Vitro Fertilisation.
The union of male and female gametes (reproductive cells) during the process of sexual reproduction.
when a sperm enters the egg to form an embryo.
Penetration of the egg by the sperm cell, which results in cell division.
union of an egg and sperm (gametes)
When a sperm cell and egg cell combine to form an embryo - the beginning of a new animal - fertilisation has occurred.
The process in which the nuclei of a sperm and ovum join to make a new living thing.
fertilization ] The combination of a sperm and an egg. ( more...)
Entry of a sperm cell into an egg: their "marriage". The egg is activated by this event, so that: (1) "cortical granules" are expelled that stop further sperm binding to the egg; (2) the second division of meiosis is completed, with expulsion of the second polar body; and (3) the machinery of the egg is got going, which will form pronuclei of the male and female chromosomes prior to syngamy.
Fertilisation or fertilization (also known as conception, fecundation and syngamy), is fusion of gametes to form a new organism of the same species. In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilisation, or outside in the case of external fertilisation.
