Embryology is a branch of biology. It involves the study of the embryo from conception until the point at which the zygote becomes a fetus.
As you should know, breathing chemicals while not pregnant is not good. Therefore, it is even worse to expose your unborn baby to harsh chemicals. Just remember, you are the life support that your baby is living on and whatever you put into your body is what also enters the body of your baby... whet…

Embryo screening checks an embryo to see if it's carrying any alleles for a genetic disease (e.g. Huntington's disease or cystic fibrosis) so that the parents would know how likely it would be for their offspring to have a genetic disease. And the reason this is often perceived as a bad thing is d…

In most birds, reptiles, insects, fish, and two types of mammals (the echidna and the platypus) an egg (Latin, ovum) is the zygote, resulting from fertilization of the ovum. To enable incubation the egg is usually kept within a favourable temperature range as it nourishes and protects the growing em…

Technically, embryology is the study of the development of embryos, the early forms of adult animals. There currently seems to be a movement to stop using the term in favor of the term developmental biology. (Personally, I prefer this term because it is both descriptive and all-encompassing -- it wo…

In the case of non-identical twins, the two embryos are from completely different eggs and are quite independent of each other and so there is no splitting into two embryos. These are the most common type of twins. With identical twins, it is the zygote that divides into two embryos, so you wouldn't…

Evolution is a gradual process, a process where genetic changes accumulate slowly over many generations. So, it's very hard to point at a single animal and say, "There is the first chicken." Rather there was a population of rather chicken like animals. Within this population mutations were occurring…

You can be safe knowing the eggs will not develop after 23 days in an artificial incubator. If temperature and humidity have been consistent then at the twenty third day nothing else will be hatching. It is harder to tell when the eggs are under a broody hen. You can mark the eggs with a date when s…

This was a research done by Hans Spemann, an embryologist of the early 20th century in Germany.

They are vis…

Embryology: In the first few days of development, a human embryo looks very similar to that of any other animal. After a few weeks, we can tell it's a vertebrate animal, but it doesn't yet look human - it could be a fish embryo! After a few more weeks, it looks like a mammal embryo, but we can't tel…

By monitoring how and what an embryo grows as it matures, you can see a lot of things that you cannot see in a fully grown animal.
