Axie genetics puzzle

[Martin21114]

Hello,

I'm trying to identify the father and figure out the genotypes of my axolotls based on their offspring. They are a mix: 40% golden albino(a/a), 15% leuc.(d/d), 15% wild type(?/?), & 30% melanoid (m/m). Based on the offspring I believe:

Tuco(melanoid female)
m/m
D/d
A/a
AX/??


Midas (suspect #1, g. albino male)
M/m
D/d
a/a
AX/??


Nugget (suspect #2, leucistic male)
M/m
d/d
A/a
AX/??


Do these seem correct? If the parents were not het for recessive traits none would have been expressed in the offspring right? I also think Midas is the dad based on the the number of albino vs leucistic offspring.

With that many albino offspring (close to 50%), the father is almost surely albino. If the male was het for albino, you'd get closer to 25% albino offspring. If the father was leucistic, you'd get 50% leucistic offspring. Since you've got a low number, the father probably isn't leucistic.

Good deduction!

Thanks for replying Kasie.

Mom-Tuco(melanoid female)
m/m
D/d
A/a
AX/??


Dad-Midas ( g. albino male male)
M/m
D/d
a/a
AX/??

This means I should I also have some melanoid albino axolotls as well, right? Aren't those are the ones that just have a little yellow on their back?
