Question

For a species with a diploid number of 18, indicate how many chromosomes will be present in the somatic nuclei of individuals that are haploid, tetraploid, trisomic, and monosomic.

Accepted Answer

Hey everyone. Let's take a look at this question. Together, humans have 23 chromosome pairs and are deployed. However, an individual has an extra copy of chromosome 13. In addition to the homologous pair identify the name of this condition. So we know that when we're talking about a mutation that is found in some chromosomes, but not all. We're talking about something called an employee which is a condition in some chromosomes but not all. And so there are four different types of an employee which are monos omi try so many Tetris army and lastly nullis on me. And so monos omi deals with that two n minus one. Trisomy is two N plus one. Tetris Omi is two N plus two and nozomi is two N minus two. And since this individual has an extra copy of that chromosome 13, in addition to the homologous pair, that would mean that chromosome 13 has three copies. And so looking at the conditions that we've listed, we can see that the one that involves having three copies is trisomy, which means that answer choice B is the correct answer because the individual that we're talking about has an extra copy of chromosome 13 in addition to the homologous pair. So that would mean that it has three copies of that chromosome 13. And that would mean that the name of this condition is answer choice B. Trisomy. I hope you found this video to be helpful.
