Why do potatoes have more chromosomes than humans?

If a woman has two X chromosomes, how do we know which X chromosome each of her offspring has? She received one X from her mother and one X from her father. Will her offspring receive the X from her mother or the X from her father? Is there a 50/50 chance of either? Or does it depend upon the offspring's sex- i.e. females receive X chromosome donated from grandmother, males receive X chromosome donated from grandfather? Do we know for sure?

I understand that the male is responsible for sex identity, by contributing the Y chromosome. Does that mean that certain traits are passed only by the Y chromosome from generation to generation? Does the male pass on the same Y chromosome that was passed to his father? Or, does the male make an entirely new Y chromosome from his father's and his mother's DNA combined?

Would you please tell me if chromosome number is a factor in identifying and distinguishing species? Why is the chromosome number of a potato and a chimpanzee the same?

Hi - I've recently become interested/fascinated by genetics; my basic question is:- 'why' is the [human] genome split into separate chromosomes rather than being one long strand and what determines[ed] which genes went to which chromosome?
