the symbol = N
N
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.
has two sets of each chromosome is designated by the symbol 2n and has chromosomes found in pairs
In a punnet square it is usually represented by a capital letter.
This is the Egyptian Symbol for the number 10.
They would produce tetraploid offspring. Reproductive cells are also called sex cells (gametes). Gametes form a fertilized egg (zygote) when they combine their chromosomes in a single nucleus. So two diploid (2n) gametes would form a tetraploid (4n) zygote. (n is a symbol for the number of chromosomes in a single set.)Scientists believe that many plants have doubled their chromosome number at some point in the past, becoming tetraploid (in some cases more than once); coffee and wheat are just two examples. This sort of thing is rare in animals.

An unknown number represented by a letter or symbol is a variable.
The atomic number.
Conventionally in chemistry, the atomic number is represented by the symbol 'Z'.

the chemical element with atomic number 2, and is represented by the symbol He
It is not, The mass number is (A). The symbol for atomic mass is (ma)
