Down syndrome involves trisomy ___. (Which chromosome is affected?) 19 5 3 21

10

Genetic mosaicism occurs __________________.   in single cells but not in tissues.   with sex chromosomes but not with autosomal genes.   in germline cells.   in females but not in males.

What type of inheritance?   Multiple choice (one answer is correct)   1. X-linked recessive 2. y linked 3. mitochondrial 4. X-linked dominant 5. Autosomal dominant 6. Autosomal recessive

I'm not sure of these. Any help is appreciated.

What is the difference between these two. How would the karytotype look like

Please help, I am confused
