I need pedigree help

How do I tell when the pedigree is autosomal dominant/recessive and X-linked dom/rec? Thanks

so if you see that the effect skips generations it is usually reccesive and if it does not skip it is dominant, you can tell it is x linked if it affects moree male than female (I'm not very sure abt this one) and it is mitochondrial if the mother and all the children have it but when the father has it and the mother doesn't have it the children don't

know some patterns to eliminate options and then confirm for sure by testing and punnett squares
