An animal embryo that has been created with animal egg and sperm. At an early stage of development, human cells are added to the embryo. The embryo will go on to develop and contain functioning human cells.
Embryos from different animals are alike because they share common developmental processes and genetic pathways. This is a result of evolution, where many animal species have retained similar genetic instructions for early development. These similarities can be traced back to a common ancestor from which these different species have evolved.
Gametes are haploid, meaning they contain half the genetic material of normal (somatic) cells. This is so that when the two different gametes fuse (during sexual reproduction), the resulting organism will once again have the correct amount of chromosomes - half from each gamete.
in animal male produce sperm(male gametes) and female produce ova(female gametes).these gametes are produces in a their reproductive organs.therefore those cells which produces these gametes are called germ cells.they are haploid.when fertilization occur then formation of zygote take place
Male gamete in flowers is pollen grain that produce in anther . When male gamete in animal is sperm that produce by testes

The ethics of researching the benefits of using chicken embryos in studying human development is a complex issue that involves balancing scientific advancement with ethical considerations. Some argue that using chicken embryos can provide valuable insights into human development, while others raise concerns about the ethical implications of using animal embryos for research purposes. Ultimately, the ethicality of this research depends on factors such as the potential benefits, the welfare of the animals involved, and adherence to ethical guidelines and regulations.

Gastrulation is a phase early in the development of most animal embryos, during which the morphology of the embryo is reorganized to form the three germ layers: ectoderm, mesoderm, and endoderm.
Fruit Flies and frog eggs are long-time,well characterized standbys in the lab environment,and specific manipulations allow researches to introduce genes from other organisms into these species
No, the majority of animal embryos develop outside the mother's body. This includes animals such as birds, reptiles, and most fish. Embryos that develop inside the mother's body are found in live-bearing mammals as well as some fish and sharks.
They have the same gametes as any other animal. Egg and sperm. Gametes are reproductive cells. All animals need this to survive and not go extinct.
Most don't. They are just unfertilized animal embryos
all sex cells are called gametes, males have sperm, female have eggs
The gametes of a male animal are produced in the testes, and the gametes of a female animal are produced in the ovaries.They are developed in these gonads from specialized cells called germ cells.
The stages of early animal development in the correct order are: fertilization, cleavage, gastrulation, and organogenesis. Fertilization is the fusion of gametes to form a zygote, cleavage is rapid cell division of the zygote, gastrulation is the formation of germ layers, and organogenesis is the formation of organs from the germ layers.
