I have a no knowledge on what a fitness marker is for Y-dna

When I was given my y-dna it stated T1b 100%, it then said I had yda Q (L245) and then J2a1b (m67).

I understand that I am 100% T y-dna but these other "fitness" indicators , are they a migrational path or do some of my DYS have similar traits to the other Y-dna's?

note- I am doing some SNP currently on my T marker

EDIT - I found info which i need to read to decide what it is for
