However if you choose r 12 elements therell be only 1 possible combination that includes every ball. 2 chromosome pairs 22 possible unique combinations for gametes. If you choose only one element r 1 at once from that set the number of combinations will be 12 - because there are 12 different balls.
Basically it shows how many different possible subsets can be made from the larger set.
Humans where n 23 gives 223 greater than 8 million combinations ignoring any crossing over. Okay back to figuring out total combinations of humans. Using that formula how many chromosomal combinations can result from meiosis when the diploid number is 16. Watch the next lesson.
