It is sexual reproduction. It is seen in both plants and animals. An egg cell (female) is produced and then fertilized by a male cell, and the two fuse to form a new individual cell.
In mammals, there are separate animals of male and female gender. The male fertilizes the egg cell of a female, which then develops into the offspring.
- In most mammals, this involves placental growth: the young develop as fetuses inside the female mother, and then are born and nursed.
- In marsupials, the young are born at a lower level of development, and continue to grow while nursing in a pouch.
- In monotremes, or egg-laying mammals, the embryo develops outside the female in an egg, then is nursed after hatching.

How do new zealand sparrows mate?
There is no New Zealand Sparrow. These common birds are the English House Sparrow, imported from UK for their sounds, and for eating insects on crops. Most birds (and fish) have a single organ called the Cloaca, (also called the Vent), which performs the functions of excretion, as well as sexual reproduction. For reproduction the birds briefly touch their cloaca together to enable the transfer of sperm. Known as a 'cloacal kiss'. There are some primitive mammals that still retain this organ, but in humans, this vanishes in embryo, to become differentiated into an anus, and a second group which offers a urinary tract, and sexual organs.

Do mammals reproduce?
Most mammals use sexual reproduction, where fertilization is internal, and give live birth.Some mammals are oviparous (egg laying) mammals called monotremes, namely platypuses and echidnas -- the young are not born live but are nursed after they hatch.Pouched mammals and placental mammals give birth to tiny young ones, so are called viviparous.Sexual intercourse

What is the form of reproduction in mammals?
Reproduction is the act of giving rise to a new offspring of the same species. In mammals, this involves sexual reproduction: the male fertilizes the egg cell of a female, which then develops as a new individual. - In most mammals, this involves placental growth: the young develop as fetuses inside the mother, and then are born and nursed. - In marsupials, the young are born at a lower level of development, and continue to grow while nursing in a pouch. - In monotremes, or egg-laying mammals, the embryo develops outside the female in an egg, then is nursed after hatching.
