It has 23 chromosomes. The fertilizing sperm has 23 as well so that together the resultant human has the normal 46 chromosome number.
The fertilized ovum, or zygote, contains 46 chromosomes. These come from the combination of 23 chromosomes from the egg cell and 23 chromosomes from the sperm cell.
Each ovum contains 22 autosomes, which are the non-sex chromosomes. This is because during oogenesis, the egg cell undergoes a process called meiosis to divide the chromosomes evenly into four daughter cells, resulting in one mature ovum with half the number of chromosomes.
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
The ovum and spermatids are formed via meiosis (which occurs only in sex cells). From meiosis, four daughter cells are produced (in the female, three of these become polar bodies, rather than ova), each with 23 chromosomes (in humans) or the haploid number (n) in other organisms. This is significant as when fertilization occurs, the zygote (sperm + ovum) will have 46 chromosomes (or 23 pairs), the normal number for a human. So, both the ovum and spermatid are haploid sex cells (gametes), each with 23 chromosomes in humans.
Female cells contain the sex chromosomes XX. A female gamete (ovum/egg) contains one X chromosome.

Each ovum contains 22 autosomes, which are the non-sex chromosomes. This is because during oogenesis, the egg cell undergoes a process called meiosis to divide the chromosomes evenly into four daughter cells, resulting in one mature ovum with half the number of chromosomes.
In an ovum, the number of chromosomes is haploid, meaning it contains half the number of chromosomes found in other cells of the body. This is because during the process of meiosis, the ovum undergoes division to reduce the number of chromosomes by half in preparation for fertilization.
spermatogenesis produces 4 sperm cells and oogenisis produces one ovum. Both have 23 chromosomes each
Chromosomes.
1 - it determines the sex if it fertilises the ovum
21 somatic chromosomes + 2 sex chromosomes (XX in an ovum or XY in a sperm).
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
The cells that have a haploid complement of chromosomes are the gametes - the ovum and the sperm.
An ovum is a haploid gamete. It contains one set of chromosomes (23 in humans) and is produced through meiosis from a diploid cell. When the ovum fertilizes with a sperm cell, it forms a diploid zygote with a full set of chromosomes.
The ovum and spermatids are formed via meiosis (which occurs only in sex cells). From meiosis, four daughter cells are produced (in the female, three of these become polar bodies, rather than ova), each with 23 chromosomes (in humans) or the haploid number (n) in other organisms. This is significant as when fertilization occurs, the zygote (sperm + ovum) will have 46 chromosomes (or 23 pairs), the normal number for a human. So, both the ovum and spermatid are haploid sex cells (gametes), each with 23 chromosomes in humans.
