How does a haploid gamete get a 1n number of chromosomes and a 1n amount of DNA?
By the process of meiosis.
What is the definition of 1n cell?
A 1n cell is a haploid cell, posessing one copy of each chromosome for that species. N=the number of different chromosomes present, 1=the number of sets of chromosomes.
How many chromosomes are in an egg if the diploid number of the liver cell is 52?
An unfertilized egg would be 1N...so the organism that has a 2N number of 52 would have a 1N number of 26.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
What is the importance of the haploid 1N Number?
The significance is, haploid 1N merely means that instead of having two sets of chromosomes (2N) there is only one set. Usually it is referred to when discussing gametes (sex cells) and sexual reproduction. Most organisms are diploid, and have that 2N formula. They have two sets of chromosomes in their sperm or egg. When a sex cell matures, it goes through meiosis, which splits the number of chromosomes from the 2N diploid to 1N haploid, so fertilization can occur. And the cycle continues...Once two cells join, and fertilization has occurred, the cell is 2N. When the organism's sex cells mature, they divide to create the haploid 1N.

Why does meiosis result 1N cells rather than 2N cells?
During meiosis chromosomes are segregated at Anaphase I stage , this results in reduction in number of chromosomes from 2N to 1N .
Why is the number of chromosomes halved?
The normal cellular genetic complement number 2N is reduced to 1N in both of the sexual gametes so that when they recombine we end up with the standard chromosome number [1N + 1N = 2N] in our zygote.

An unfertilized egg would be 1N...so the organism that has a 2N number of 52 would have a 1N number of 26.
What cell is a haploid?
A haploid cell contains 1n (half) the number of chromosomes as an normal, 2n, cell.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
If a organisms has 500 chromosomes how many will be present in each cell through process meiosis?
250 would be the 1N number after meiosis.
Biologists use what symbol to represent one set of chromosomes?
The number of chromosomes in a cell is represented by the letter "n". A cell can be haploid (n or 1n), diploid (2n), triploid (3n), etc. A gamete is haploid and would be represented by n, or half of a diploid (2n). Some notations will say the chromosome number (in humans for example), n equals 23 or n=23. Likewise, a diploid cell would be denoted by 2n=46.

How many pairs of chromosomes in human haploid sex cell?
Its ploidy is 1n.
How many chromosomes in a spermatid?
A primary spermatocyte will have 46 chromosomes or chromatids. Primary spermatocytes are diploid cells. Secondary spermatocytes are haploid cells with only 23 chromosomes.
