Question

How does the genetic makeup if the cells that result from mitosis compare with the genetic makeup of the original cell?

sorry i ran out of room so ill type the whole question here. i dont get it for biology lab can someone help me in a more detailed way?

Answer 1

The genetic makeup of the 'daughter cells' that are a product of mitosis should be identical to that of the cells they were created from. However, cellular copying of DNA is never 100% perfect, so each subsequent generation of cells will have some changes (mutations) in the DNA.

Additionally, the telomeres at the end of the DNA strand in each chromosome shortens with each mitotic replication (with the production of each new generation of cells).

Answer 2

Actually, the genetic makeup of cells that result from mitosis are somewhat blended since this is where and when chromosome swapping or 'recombination' takes place. Here, alleles are interchanged between chromosomes, so one chromosome with genes A b c D could end up with genes aBcD or ABCD or aBcd....and on and on and on...
