In this cross the trait of long tail fins is associated with the “Y” chromosome of the male.  
Thus the alleles  of the male are represented by XY” where X chromosome has no trait of long tails find  
And the allels of the female are represented by XX, as they do not have long tail fins.  
When these two are crossed , the following punnet square is produced
 X     Y”
X	X X    X Y”
X X X     X Y”
The XX is the female while the XY” is the male offspring.
