How many chromosomes are in one gamete
WebAs we have already seen, the letter n is the number of chromosomes in a gamete, and 2n is the number of chromosomes following fertilization. To distinguish polyploids, the letter x is used to represent chromosome sets. For example: For a tetraploid 2n=4x and a gamete has n=2x chromosomes. For a hexaploid 2n=6x and a gamete has n=3x chromosomes. WebWe would like to show you a description here but the site won’t allow us.
