In one mitotic division, 2 daughter cells are formed from 1 parent cell.
In 3 generations, no.of cells will be 2³ = 8.
50% of the cells again undergo 4 generations of mitosis.
50% cells = 8×(50/100) = 4 cells
cells not undergoing division = 8-4 = 4
in 4 mitotic division, number of cells produced from 4 cells = 4×2⁴ = 4×16 = 64
total cells = 64+4 = 68
In 3 generations, no.of cells will be 2³ = 8.
50% of the cells again undergo 4 generations of mitosis.
50% cells = 8×(50/100) = 4 cells
cells not undergoing division = 8-4 = 4
in 4 mitotic division, number of cells produced from 4 cells = 4×2⁴ = 4×16 = 64
total cells = 64+4 = 68
kriths:
number of cells produced by 4 cells in mitotic division is 8 right?
in 1 generation...but they undergo 4 more generation naa...
sorry i didnt understand :p
:)
they go four more generations? wait....isnt it gonna go through just one more extra mitosis? o_O
" 'again' undergo four generations of mitosis" - not 4th generation
ooohhhh......tnx ^-^
u saved my marks!

Answer:
68
Explanation:
1 cell⇒3 divisions⇒8 cell, out of this 50% i.e., 4 cells undergo another 4 generation...
i.e., 4 cells⇒4 mitosis⇒4*2^4=64
4 cells from 1st and 64 from second, total 68 cells
