Question

Certain varieties of chrysanthemums contain 18, 36, 54, 72, and 90 chromosomes; all are multiples of a basic set of nine chromosomes. How would you describe these varieties genetically? What feature do the karyotypes of each variety share? A variety with 27 chromosomes has been discovered, but it is sterile. Why?

Accepted Answer

Hello everyone and welcome to today's video. So the reason behind sterile hybrid plants is the failure in fertilization, which of the following correctly describes failure. Let's begin by answer choices A. M. B. And the reason why we're looking at them together is because gametes and chromosomes are very important in reproduction. Now if the government fell to unite our power up or the number of chromosomes from the parents doesn't match, then we are left with sterile plants. These are correct answer choices. So we're not going to cancel them out. Then we have seen some male plants don't produce pol. Um remember that pol. Um is the male gami just like sperm? Is the male gami in humans? Now if these male plants are not able to produce pol, um then there's going to be a failure in fertilization is just not going to happen. So this is also going to result in sterile plants and it is going to be also a correct answer choice now because all of our answer choices are correct and we were not able to cancel out any of them. We're going to select the all of the above as the correct answer to our question. I really hope this helped you and I hope to see you on the next one.
