if you are missing one pair of chromosomes in a cell, what type of mutation would you have?

Question

i was studying a karyotype and realized that there was an extra chromosome. what chromosomal mutation would that be if you had an extra one.

Answer 1

It's not a mutation, per se, because it doesn't involve a change in the DNA, just a malfunction in the production of germ cells. What disease it is depends on which chromosome you're talking about.

- Down Syndrome is an extra copy of chromosome 21. This is the most frequent extra chromosome aberration in the population.
- Edward's Syndrome is an extra copy of chromosome 18. This is the second most frequent.
- Patau Syndrome is an extra copy of chromosome 13.
- Klinefelter's Syndrome occurs in men with two X chromosomes and one Y.
- XYY Syndrome is (obviously) a man with an extra Y.
- XXX Syndrome is a woman with an extra X. (And has nothing to do with Vin Diesel).

I'm sure there are more, but they start to become really, really rare. I'd provide links for all those diseases, but there's so many of them! Hope that helps!

Answer 2

The state of having a missing chromosome pair is called aneuploidy. It is not a disease. Since it is rare for an organism to survive with even one of the two copies of a chromosome missing, missing two would be catastrophic (given how many genes are on each chromosome, and how many of these would be absolutely necessary for the cell to grow and divide), and the newly dividing cell would most likely not survive past a few divisions, and assuredly would not come to term.

Answer 3

Sexual duplicate desire no longer have started in the form you describe. it could nicely have started as a sort of hermaphroditism, the place organisms, jointly as seeming an identical, a fashion or the different began to share their DNA, or, as contained in relation to micro organism, some DNA is encapsulated interior the plasmid, and shared with different micro organism. From right here, is it the type of bounce to have faith that one mutated micro organism grew to become into shaped that had merely the only variety of DNA, say, the plasmid, for occasion, and shared that around with greater micro organism than dividing on my own might produce. Or a hermaphrodite grew to become into born lacking area of its DNA, however the area which remained ought to bypass itself directly to greater companions than different organisms. this could be a simplified version, yet those eventualities at as quickly as are evoked, and don't desire the accident of two mutations happening on an identical time, a male and a female, interior an identical place. different, greater expert respondents would clarify it greater useful, yet you ought to have the potential to settle for the solutions as given. There are too many issues of creation for me to settle for it without information. i don't experience affronted by potential of realising that i'm on the subject of Apes, monkeys and pond slime.

Answer 4

I know if you have extra you would turn out pretty much a giant and have a shorter life span.

Answer 5
