much like periods in women, hens lay unfertilized eggs because they are always producing egg shells (made of keratin and protein). when not fertilized they hen must get rid of it by laying an egg. most egg farms will only have hens to produce edible eggs which must be unfertilized in order to be told to the food market.
Zygote is immediately produced when an animal's egg cell is fertilized by the sperm.
The union of egg and sperm results in the formation of a fertilized egg or zygote. This marks the beginning of the development of a new individual with a unique set of genetic characteristics.
Oviduct is where the egg cells are fertilized while the ovary is where the egg cells are produced and where they mature.
An egg is produced in the ovary, released into the fallopian tube during ovulation, fertilized by a sperm in the fallopian tube, then travels down to the uterus where it implants in the uterine lining for further development.
It is necessary for an egg to be fertilized so the egg can hatch.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Yes, a zygote is a fertilized egg.
Eggs are produced in the ovaries of females, while sperm are produced in the testes of males. The meeting of egg and sperm typically occurs in the fallopian tubes, where the egg is fertilized by a sperm to initiate pregnancy.
Moss egg cells are produced by the female reproductive organs called archegonia in moss plants. The archegonia are responsible for producing and releasing the egg cells, which are then fertilized by sperm cells to form a zygote.
No it isn't. Eggs sold as food in grocery stores or supermarkets are not fertilized, they have received no sperm. The egg is produced entirely by the hen, with no contribution from the rooster. Even if the egg has been fertilized, the sperm is microscopic, and it only contributes to the genetics of the resulting embryo, not to the egg white.
When a bird's egg is fertilized, a chick is developing inside.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
