The answer is 48. A megaspore mother cell is 2n before is begins meiosis.

Are spermatids haploid?
Four megaspores are formed from meiotic division of megapore mother cell which is diploid. We know that diploid cells undergo meiosis to give haploid cells. So, it seems to me that megaspores are haploid.
How many sex chromosomes are in a diploid cell?
the diploid number of chromosomes is the number of chromosomes that organism is haploid for times 2. It looks like this: 2n. Humans have 23 chromosomes each. So the mother has 23 chromosomes (this # is the haploid # of chromosomes for humans), plus the father who also has 23 chromosomes, is the diploid number of chromosomes, 46.
What happens to a megaspore mother cell and a microspore mother cells as an immediate result of meiosis?
The megaspore mother cell and the microspore mother cells split in half.
The offspring will have traits of both the mother and father Why?
during fertilization 23 chromosomes are coming from mother and 23 are coming from father and so a diploid condition is establishes in the zygote
How many chromosomes produce a cell?
In humans there are 23 pairs of chromosomes in a diploid cell (a normal body cell e.g. a skin cell) However there are just 23 single chromosomes in a haploid cell (a sex cell e.g. a sperm) this is because when fertilisation takes place the embryo has a total of 46 chromosomes, as it takes both haploid cells, making it genetically identical to both it's mother and father, and making it a diploid cell.

What is meant by diploid chromosomes number?
Diploid mean double.Two set of chromosomes (23) from father and (23) from mother.
What are diploid chromosomes?
A pair of chromosomes, one from the mother and one from the father that are similar.

If gametes were diploid like somatic cells how many chromosomes would the zygote contain?
If gametes were diploid, that would mean the zygote would get 46 chromosomes (in humans that is) from his father and 46 chromosomes from his mother, that would add up to 92.
Why is the cell called a diploid cell?
Unlike the haploid cell which consists of one chromosome, the somatic (diploid) cell contains two chromosomes (one from the mother and one from the father)
What is a cell that contains both sets of a Homologous chromosomes?
A cell containing both sets of homologous chromosomes is called a diploid. One is usually taken from the mother and one from the father.
What is the purpose of the diploid cell?
A diploid cell is the result of the combination of two parental cells. For example, via meiosis in humans, different chromosomes are extracted from both parents which then combine into creating 23 chromosome pairs for fetus. Diploid cells are commonly referred to as "2n", as Haploid are "n". In humans, this stands for 2n = 46, which is our total number of chromosomes. Diploid cells are what cause genetic variation among populations due to the fact that they combine different chromosomes from different receptors
The offspring will have traits of both the mother and father Why?
during fertilization 23 chromosomes are coming from mother and 23 are coming from father and so a diploid condition is establishes in the zygote
How doe meiosis realte to reproduction?
Meiosis is a complex cell division process in which the diploid number of chromosomes of the mother cell is reduced to haploid number of chromosomes in 4 daughter cells. IT TAKES PLACE IN EUKARYOTIC DIPLOID GERM CELLS OF THE SEX ORGANS OF PLANTS AND ANIMALS
What is the difference between microspores and megaspores?
microspores are the male gametes whilst megaspore are the female gametes. megaspore also known as megaspore mother cellor megasporocyte. it placed in female cone in the gumnosperm while the microspores placed in the male cone
