Hi, i need help in understanding what syntenic relationship means between species. for example if we take the mouse gene A on chromosome 5 and a equivalent gene in human B located on chromosome 16. if they have a syntenic relationship, does that mean that human gene B was previously located on human chromosome 5 and through chromosomal rearrangement became located on chromosome 16, or does it mean that similar genes are likely to be found flanking the B gene in humans and the A gene in mouse???????
