A pea plant has 14 chromosomes. Calculate how many different combinations of chromosomes can be produced in the offspring?
Chromosomes come in pairs so 7 pairs, one from each pair, so that sounds like 2^7 = 128 different combinations possible from each parent
128 possibilities from 1 parent * 128 possibilities from the other parent makes 128*128 = 16384 possibilities for the offspring of 2 specific parent plants.
BUT I am basing this on my limited understanding of genetics. I have no idea what your teacher meant. The question is very incomplete.
