neurula and then tadpole
If the sperm cannot get into the egg, fertilization cannot occur and pregnancy will not take place. The egg needs to be fertilized by the sperm in order for the genetic material from both to combine and form a zygote, which will eventually develop into an embryo.
Differentiation is important during embryonic development as that is the timeframe for specialization. Differentiation allows for neurons, blood cells, skin and muscle cells organize into tissues, then organs, and ultimately into systems.
The presence of a sperm penetrating a polar body suggests an abnormal fertilization event, as polar bodies typically do not contain a full set of chromosomes needed for normal development. Therefore, the resulting cell would likely have an incorrect number of chromosomes, leading to genetic abnormalities that would prevent the development of a healthy embryo.
One would think it's embryo but a zygote is not a embryo yet, it is the early stage of what will become a embryo. Zygote is the word used and you can use the word cell since a zygote is the initial cell formed after a sperm and egg have joined. After 1 week it has transformed into a embryo.
Inside a seed, you will find an embryo, which is the early stage of a plant. Along with the embryo, there is also stored food supply, usually in the form of endosperm or cotyledons, to provide nutrients for the embryo to grow and develop into a new plant. The seed is protected by a seed coat, which helps to keep the contents safe until conditions are right for germination.
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )
The embryo will develop into a foetus in the womb.
It probably has to do with the predetermination of the baby's sex. If the father contributed a Y chromosome, then the indifferent gonads would develop into testes. If an X was contributed then they would develop into ovaries.
If the chick embryo's cells did not specialize, it would not be able to develop into distinct tissues and organs necessary for survival. Specialization is essential for the proper function of different cell types in the body, and without it, the embryo would not be able to form a fully functioning organism.

Eventually, it has a detrimental effect on your health. You would develop some problems.

The embryo/fetus would die.
No, the separation of an egg and its polar body after fertilization does not typically harm the development of the embryo. The polar body is a byproduct of egg cell division and its removal does not affect the genetic material necessary for embryo development.
It would likely result in developmental defects, leading to abnormal formation of organs in those specific parts of the embryo. This could affect the overall development and function of the organism.
Eventually you would develop diseases caused by malnutrition and vitamin deficiencies. Scurvy, as an example. Guns bleeding and teeth falling out.
