Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.
In a typical scenario, a fertilized egg receives half its chromosomes from the egg cell and half from the sperm cell. If there are 194 chromosomes in each body cell, the sperm would also have 97 chromosomes (half of 194). Therefore, the fertilized egg would have 97 (from the sperm) + 100 (from the egg) = 197 chromosomes.

there are approximately 69 in a sperm cell and approximately chickens in an egg
The egg cell of a weed will typically have half the number of chromosomes as a normal body cell of that weed species. This is because the egg cell undergoes meiosis to reduce the chromosome number in preparation for fertilization.
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
A lily's egg cell typically has half the number of chromosomes found in its somatic cells. Lilies (genus Lilium) are generally diploid, meaning they have two sets of chromosomes. Therefore, if the diploid number is 24 chromosomes, the egg cell would have 12 chromosomes.
