chromosomes
all cells of body except egg and sperm have 23 pairs of chromosomes i.e. 46...but egg and sperm have 23 chromosomes
In humans there are 23 single chromosomes. In a zygote there are 23 pairs.
Normal egg cells are haploid and a haploid cell can`t have pair of chromosomes.Pair of chromosomes actually means homologous pairs of chromosomes which are not present in eggs. Human egg contains 23 unpaired chromosomes and Drosophila egg contain 4 unpaired chromosomes which can`t be called 2 pairs as they are not homologous. Some abnormal eggs eg of parthenogenetic animals may possess paired chromosomes.
The human egg or sperm cell is haploid and contains 23 chromosomes. After fertilization (egg and sperm fusion), the zygote will have 46 chromosomes (23 pairs).
All human cells , with the exception of sperm and egg cells, have the same number of chromosomes (46). Sperm and Egg cells have half that number.
Humans have 23 pairs,werewolves have 24 pairs,and vampires have 25 pairs.
it is important for 1 sprem to fertilize a human egg (Ova) in order to start the conception process. If 2 sprem Cells fertilize the 2 DIFFERENT Ova the mother will have "Fraternal Twins". However, if 2 sperm cells fertilize the SAME Ova (egg) the mother will have "Identical Twins". I hope that is the answer you were looking for?
A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA. If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.
In a human cell we should have 46 chromosomes in 23 pairs. We get 23 of these chromosomes from the male gamete (sperm) and the other 23 from the female gamete (egg).
The sex cells, or gametes, (egg and sperm) don't contain pairs of chromosomes. They each contain 23 singular chromosomes. When the egg and sperm combine, the resulting cell will have 23 pairs of chromosomes.
Chromosomes in a body cell are typically in pairs (diploid), with one set inherited from each parent. In contrast, chromosomes in a fertilized egg are also in pairs, but contain a unique combination of genetic material formed from the genetic contributions of both the egg and sperm, resulting in a single set of chromosomes (haploid) in the fertilized egg.
