Help with gender and mutation please

[Suze]

Hi!
I‘m new here, and this is my newest little Love, Grover.  I can’t quite work out what type of pied he/she is? Help please 😃.  I thought it looked like it’s gone through the first molt, though I do see extremely faint lines on the forehead still- so not sure if that’s related to the recessive genes instead?  

The cere made me think it’s male(?). Any thoughts would be appreciated.  

As to the mutation-  I tried to get photos that show all the white and the location of the blue coloring.  I got the tummy for reference and the back, face.  I did notice the back feathers are more of a brownish grey.  The shoulders at top of wing are black/great. Eyes are black, no visible iris, and have that tan/pink ring around them.  

Thanks so much for the help.  This is my first recessive mutation budgie, and I keep getting confused between SF dominant, clearwing, etc.   

Cheers!  Susan 

Hope I got the photos right.  🤪

Dominant pied male. If he has only just gone through first moult the iris rings will not yet have visibly started to form.

Oh my word. My Kevin has a double... Right down to the white patch on the back of his head! Suze

There should be a pic on this but it hasn't appeared... I'll try again.

The white patch at the back of the head is a pied patch. All pieds (should) have it.

Oh thanks Hezz that's really interesting. I know nothing about gender and mutation, except that now I know that the Kevster is a dominant pied.

Thanks so much for all your help, everyone! I just love little Grover, and happy to learn what his variation is. Thanks again!
