XY Factor Breeding Pedigree

Trace the genetic path using the chromosome trail....
MALE PUPS ARE XY ~ FEMALE PUPS ARE XX

A male pup gets a Y chromosome from his father, who got it from his father and so on.

He also gets an X chromosome from his dam...

Female pups are XX ~ They get one X from both parents.
The big question is ???
 
Which X Chromosome out of the Dams XX pair is passed to each individual puppy...

Dogs on BOTH sides of Pedigree are Italicized.

Key dogs which are on both sides of pedigree in key positions are the same color.

BLACK HOLES HAVE WHITE BACKGROUND.

Start out by numbering a copy of your 4 generation pedigree the sire is
1, dam is 2 the paternal grand sire is 3, paternal grand dam 4, maternal
grand sire 5, maternal grand dam 6, back to the top with the paternal

_________

Here's how to figure it out...

_____________________________
On a bitch PUPPY pedigree (XX)

The key positions are 1,2,4,5,6,9,10,12,13,14,20,21,22,25,26,28,29 and 30.

The strongest x factor are the bitches in positions 2,6,14 and 30. They
are the tail female line because that x chromosome is passed along with
the lease amount of change (mosaic).

The Black Holes are in positions 3,7,8,11,15,16,17,18,19,23,24 and 27.
Because the dog (xy) that proceeds it only past his Y chromosome. So
because a bitch is (XX) it takes these dogs out of the equation.
_____________________________________

After doing that...

Here are the key positions for a Male Pedigree (XY) 1,2,3,5,6,7,11,12,13,14,15,24,25,26,28,29 and 30.
Basically the sires side is the only one that changes.

Again the strongest X factor are the bitches in positions 2,6,14 and 30.
The "tail females".
However the "tail males" are the males whose Y chromosome gets passed
along with the least mosaic they are in positions 1,3,7 and 15.

The Black Holes on a male dogs (XY) pedigree are in positions
4,8,9,10,16,17,18,19,20,21,22 and 27. Remember only the Y chromosome is
being passed along on the sires side.

great grand sire is 7, now straight down ending with 14 then back to the
top again numbering 15 thru 30.
