Because mitosis creates duplicates of cells with complete copies of the chromosomes in each cell made. For eggs and sperm cells the cell division process has to end up with the eggs and sperm having just 1/2 of the chromosome numbers in each cell made. Eggs and sperm are therefore produced by 'meiosis' and not 'mitosis'.

There are some cells that can not go through Mitosis In other words an organism can not make any new ones when the cells die Human nerve and muscle cells are examples?
That's correct. Nerve and muscle cells are examples of cells that are incapable of undergoing mitosis to generate new cells once they have matured. This is due to their specialized functions and structures that make it challenging for them to divide and replicate. Instead, these cells are typically replaced through repair processes, such as tissue regeneration or repair by stem cells.
Can you breed animals using their DNA?
no and yes. you cant breed animals simply from dna collected from a saliva or hair sample. how ever and ovum (egg cell) and sperm cell without dna would not have a reaction. you need two sex cells from animals of opposite genders if the same species and the cells have to have undergone mitosis (you cant merely put dna from any part of the body into these cells and expect anything to work they need to go through a process which involves reconfiguration of the individuals dna chromosomes for the cells to be viable)
Pregnant with toys?
no you cant because the sperm from a boy has to touch your vigina and a toy cant give sperm.8==>
Why cant sex cells form by mitosis?
Sex cells cannot form by mitosis because they need to undergo a special type of cell division called meiosis, which reduces the chromosome number by half. This reduction is essential for sexual reproduction to ensure that the offspring receive a unique combination of genetic material from the two parents. Mitosis, on the other hand, results in daughter cells with the same chromosome number as the parent cell.
Why cant female cats have babies without a boy cat?
Because that's how sexual reproduction works. Both egg and sperm are needed to create offspring.
Can a girl get pregnant from sperm on thigh?
No, a girl cant get pregnant from sperm on thigh........
Why does crossing-over not occur in mitosis?
Crossing-over only occurs during meiosis, not mitosis, because it is essential for genetic diversity in gametes. In meiosis, homologous chromosomes pair up and exchange genetic material during crossing-over, increasing variation in offspring. Mitosis, on the other hand, involves the duplication and division of cells for growth and repair, without the need for genetic recombination.
Why cant men make babies?
Okay, The Reason Is... - Men Don't have The Egg Cell ( Women Only Have Egg Cells ) Note: Some Men Were Born Or Placed With Egg Cells and Sperm Cells At the Same Time That's How Some Men Get Pregnant....
Is 1.2 million per ml sperm count can father a child?
Yes ! Remember - it only takes a single sperm,meeting an egg to create an embryo !
Can Adam release sperm?
no, he cant and never will
If you are gay can sperm in your body give you worms?
you cant get worms from sperm.....gay or straight
What is wrong if you cant bust a nut?
because your body has not produced sperm cells
