The fertilized egg is in the eggshell. It is an extremely large egg. It fills the egg shell. It is larger than the chick will be when it hatches! It divides like any other cell and becomes smaller.
A fertilized egg splits in two- Apex
When twins are formed from one embryo, it is known as monozygotic twinning. This occurs when a single fertilized egg splits into two embryos. As a result, the twins will share the same genetic material, leading to identical or monozygotic twins.
During meiosis, a type of cell division that produces gametes (sperm and egg), DNA is replicated once, followed by two rounds of cell division. The process results in four daughter cells with half the number of chromosomes as the parent cell, leading to genetic diversity through recombination and independent assortment of chromosomes.
Identical twins have the same genotype because they have the exact same genes. Identical twins are formed when one fertilized egg (zygote) splits in two and each of the now two zygotes each develop into different beings. Identical twins are therefore referred to as monozyygotic twins and they have the same DNA.
Conjoined twins are monozygotic, meaning they develop from a single fertilized egg that splits incompletely during early development.
it is lost in menstruation
in the uterus
It breaks down/ Is removed through the vagina.
Depends on whether you're having sex or not.
It gives them a better chance or increases the odds of having atleast one egg fertillized.
egg splits
Under ideal conditions, Dark, damp and cool, a fertilized egg can still be viable for up to 7 days. Eggs left in a nest with no broody hen to set on them should be thrown away after day 8. They will not be suitable for hatch or for eating.
A twin is on the way
no. one egg is fertilized and it splits up later on.
The egg is fertilized in the fallopian tube in the woman's body.The eggs come there and the sperm fuse there with them.There are two tubes.
The fertilized egg will attach itself to the inner lining of the uterus, the endometrium, in most cases. In some instances, it may implant itself into the Fallopian tube, which results in an ectopic pregnancy that can be fatal to the mother and fetus.
Random bases attach.
