So here we have a pretty straightforward example problem that asks, in an alteration of generations life cycle, which of the following is true? And we've got these 4 potential answer options down below. Now option a says, the organism alternates between multicellular diploid and multicellular haploid forms. And of course, this is going to be a true statement. This is really what the alterations of generations life cycle is all about.
Cycling or alternating between multicellular diploid sporophytes and multicellular haploid gametophytes. So option a is a true statement. Now option b says male gametophytes produce sperm while female gametophytes produce eggs. And once again, option b is a true statement. Now option c says organisms may look different during the two parts of their life cycle.
Now if the organisms look different during the two parts of their life cycle, meaning the sporophyte looks different than the gametophyte, then we call this heteromorphic. Now, if the sporophyte and gametophyte look identical to each other visually from the outside, then we call that isomorphic. But answer option c is a true statement, and so really what we're saying is that it's actually answer option d, all of the above that is the correct answer to this example problem. So that concludes this problem, and I'll see you all in our next video.
