Gametes form in a cell division process called meiosis, in which a cell splits into four copies instead of the usual two so that the gametes contain half the normal number of chromosomes-just one of each of the 23 pairs normally found in human cells. 'Chromosomal crossover' occurs during ...

What are the two type of gametes? Gametes: In sexually reproducing organisms, body cells are diploid, meaning that they have two sets of chromosomes. Meiosis is the process through which gametes form, and it cuts the number of chromosomes in half. The gametes that are formed by meiosis are...
What are gametes, and how do they produce a diploid cell with the normal chromosome number?Types of cellCells in multicellular organisms can be somatic (body cells) or gametes (sex cells). These cells differ in function, structure and number of chromosomes contained....
Morphological screening for large pollen grains and shape of pollen produced by the individual, cytological investigation of hybrid progeny, and unbalanced separation of chromosomes at anaphase I in pollen mother cells were used to detect the gametes with somatic chromosome number in Fuchsia . The ...

Haploid Number The haploid number is the number of chromosomes within thenucleusof a cell that constitutes one complete chromosomal set. This number is commonly denoted as "n" where n stands for the number of chromosomes. The haploid number is unique to the type of organism. ...
During the process the gamete chromosomes are first duplicated, then the cells divide twice, producing cells that have one set of chromosomes, called haploid. When two individual haploid gametes fuse to produce offspring, a diploid cell called a zygote, the original chromosome number is restored. ...
