A zygote is formed from the union of two gametes. The number of chromosomes differs from different species, but in humans, there are 46 chromosomes. 23 from the male gamete and 23 from the female gamete.
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.

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.

The egg cell would also have 20 chromosomes because during sexual reproduction, each parent contributes half of the chromosomes to the offspring. This ensures the offspring will have the correct number of chromosomes for the species, in this case, 20 chromosomes for the lizard.
