Use your knowledge of genetics to explain how a karyotype like this could arise.

deletions can happen and you can have inherited them

it's funny that you got the same chromosome 16 though

https://en.wikipedia.org/wiki/Trisomy_16

basically at an early stage you were supposed to die because you had a trisomy 16, because your mom is old and she had a disjunction issue in her egg

BUT, after the first few divisions some cells who had too many chromosomes died ( the cells that had your dad's 16 chromosome too ) so you were left with cells that only had your mom's 16 chromosome

There's other less likely scenarios where your dad didn't give you a chromosome 16, your mom and dad are related (unlikely due to recombination)

is where you false flag

Also one day if you plan to have kids your wife will be at a higher risk because some of your cells might contain trisomy 16, but once the fetus has reached the first three months, then the fetus is most likely normal

this is because some of your sperm cells will carry 2 chromosome 16(abnormal), some will carry one (normal)

Wouldn't that only happen if the gametogenic cells had trisomy? According to the readout, chromosome 16 copy numbers are normal.

As for the deletions though, I could see that causing some sort of problem.

I thought a karyotype is a photo or an image of all the chromosomes of an organism, arranged in an array.

>Wouldn't that only happen if the gametogenic cells had trisomy?
they do though, some do anyway

they start out as a cell with 46 chromosomes, they divide into 2x23
BUT if one of them has 47, then one will have 24, the other 23
i don't really know desu

if deletion is not in some important part, then it's ok, you'd think 23andme compared the total chromosome and not just coding parts
>>
>>8864615
Thats true, this is a digital karyotype.

>they do though, some do anyway
Why?
