There are 23 chromosomes in a human haploid cell.
Twenty-three unpaired chromosomes are found in a human haploid Cell. Twenty-two are X and the Chromosome Number 23 is either an X or a Y.
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.
ploidy is the classification based on the number of homologous chromosomes present. if there is only one pair of homologous chromosomes then the nucleus is said to be haploid if there are two pairs then it is known as diploid if three it is triploid if many it is noted as polyploidy --------------------------- an oocyte or a spermatocyte are haploid cells in a species that normally have diploid cells.
They do not have pairs since they are haploid. They have 23 single chromosomes.
Its ploidy is 1n.
haploid
Haploid cells have no pairs of chromosomes.
There are 3 billion base pairs per cell in a human diploid.
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).
Yes, the haploid number of a cell (or, to put it another way, a species) is the same as the number of pairs of chromosomes in a diploid cell.For example, we humans have a haploid number of 23. This means that a diploid cell has 23 pairs of chromosomes.

If you're talking about a human cell, then no. Diploid means you have two complete sets of chromosome. For a human, this would be 46. A human cell is haploid when it has only 23 chromosomes - this is the case for the sex cells: sperm and egg each have 23 chromosomes.The issue can be confused if you discuss chromosome pairs...in which case, 23 pairs of chromosomes in a human cell makes it a diploid cell.
As you may know, almost all our cells contain pairs of chromosomes - 23 pairs to be exact. These are called diploid. Haploid cells contain only one chromosome from each pair. Reproductive cells (both male and female) are haploid, so they can fuse and form a diploid cell with chromosomes from both the male and the female. The female reproductive cell (which is haploid) is the ovum, or egg cell.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
