Consider a diploid cell that contains three pairs of chromos

Consider a diploid cell that contains three pairs of chromosomes designated AA , BB , and CC . Each pair contains a maternal and a paternal member (e.g., Am and Ap , etc.).

During meiosis, assuming no crossing over, are any possible combinations present during prophase II of meiosis other than Am Bm Cm , Am Bm Cp , Am Bp Cp , Am Bp Cm , Ap Bm Cm , Ap Bm Cp , Ap Bp Cm and Ap Bp Cp? Yes or No

Solution

No of possible combination would be 2ⁿ where n is no of chromosome pairs

so 2³=8 so we have 8 possible combination

a) Am, Bp, Cm
b) Ap, Bp, Cm
c) Ap, Bp, Cp
d) Am, Bm, Cp
e) Am, Bp, Cp
f) Ap, Bm, Cm
g) Ap, Bm, Cp
h) Am, Bm, Cm

draw a cell and draw the three pairs of chomosomes, AA, BB,CC. You know that one ABC with go to one cell and the other ABC will go to the other cell. The Am could go to one cell the the Ap could go to the other cell. There is no set arrangemet of which A, maternal or paternal, will go to which cell, so there are many combinations!

So answer would be No- no other than that 8 possible combination
