Do human female eggs have yolks?

Question

Well you never know unless you ask!!

Answer 1

It has a nucleus, not quite a yolk.

Answer 2

Yes, because like in any other female animal, the yolk in the source of first ''food'' for the developing foetus. These yolk spots in the fertilised ovum are present for a short period of time until the placenta (umbilical cord) forms, in humans.

The food that the foetus needs is NOT stored in the nucleus because that's where all the genetic material, the DNA, is fusing. Also, the food is not stored in the cytoplasm because this is where the vital chemical reactions are taking place like the production of hormones that's going to keep it alive.

NB. These yolk spots only become present when the egg has been fertilised.

Answer 3

The human female egg, whether fertilized or unfertilized does not have a yolk, but a yolk sac develops later in the embryo. An egg yolk provides nutrient for a developping embryo. Since mammals (except a duckbilled platypus) have placentae, they do not need this structure except very early in development. The human yolk sac develops into a vitelline structure which carries blood from the embryo to the placenta and vice versa.

Answer 4

Actually, during the early stages of development a female egg does have a yolk sac. This is the site for early development of blood vessels. Once the fetus has matured the yolk sac becomes associated with the umbilical cord.

Answer 5

A human female egg is a single cell which once fertilized by a sperm develops into an embryo and implants in the womb. Eventually, the placenta develops, this interfaces with the mother to allow nutrients to pass to the embryo. So the closest comparison in people to the eye's yolk, would be the placenta.

Answer 6

No. Yolk is the food supply for the developing embryo of animals that hatch from eggs laid OUTSIDE the body (eg birds, reptiles etc). Human eggs attach to the lining of the womb and the embryo gets nourishment via the placenta.

Answer 7

No, they have yolk sacs instead. The yolk sac contains vitelline fluid which may be used to provide nutrients for the embryo in its initial stages of development.. Human ovum does not need to store food in yolks as the foetus can obtain its nutrients from its mother via the umbilical cord.

Answer 8

no they don't have yolks. humans don't develop inside eggs. the "egg" in women is the is a reproductive cell. After it beomes fertilized, an embryo develops in a sack (which you may wold be like an egg shell). Chicken aggs have a yolk to supply food to the embryo while it develops outside of its mother's body. Our "eggs" develop inside the mother and have a constant supply of food through the placenta. There is no yolk necessary.

Answer 9

No because we are not birds.Birds lay eggs and the developing embryo takes its nutrition from the yolk.We humans do not need a yolk as nutrition comes from the mother via the placenta and umbilical cord.

Answer 10

No, the reason is that female eggs are way diffrent than animal eggs. Animal egss have yolks in them, what do you think is in the eggs that we buy at the grocery store. Female eggs can't have yolks in them another reson is that we can't eat human eggs so how would they have yolks in them.

Answer 11

the female egg is the same concept as a bird egg without the hard shell. The hard shell is necessary for growth outside the body. In fact all reproductive eggs are the same in concept.
