100% Het X 100% Het... Question

I'll use a Pied as an example. Is a Pied required to produce a Pied, or can you produce one by breeding two 100% Hets?

Breeding 2 hets together will give each egg:
25% chance of being a pied
25% chance of being a normal
50% chance of being het for pied

Thanks for the reply, FB. Have you, or anyone else, ever bred two 100% hets and got that morph?

I have...

I have also done Het to Visual, and gotten Visuals.

It all works.. :)

Go read on genetic and you will understand.

Let's do a Punnett square...

1. trait: Piebald
2. key:
NN normal
Nn normal
nn piebald
3. P1: Nn x Nn
4. F1:
... N n
N NN Nn
n Nn nn <---- BINGO
5. genotype: NN (normal), Nn (normal 100% het pied), nn (pied)
6. genotypic ratio: 1:2:1
7. phenotype: normal, pied
8. phenotypic ratio: 3:1 (that's where the term 66% het comes from... the normal is not physically different from the hets, so you can't be sure which is het)

Hope that helped.

not to interupt your thread M&J but this might help you also. DutchHerp or anyone else who can, Can you show me how to do a punnet square for a Spider het hypo X het hypo? thanks

It works course those are odds and sometimes you are lucky and sometimes you're not

I will let you know how it work for me in a little over 2 months ;)

Well with spiders/dominant morphs I think of it like this... just leave out the dominant morphs and when you get your offspring, half of those will also be spider. So you're get normals, het hypos, and hypos from that offspring... but half of those should theoretically also be spider, so hypo spiders. You have a 1/8 chance of getting that.

so then with spider het hypo x spider het hypo you would get 25% honey bees, 50% Spider het and 25% spider?

A honey bee is a hypo spider right?

If so, then yes, you're right.

close you could also get normals and het hypos. spider is a co-dom not dom just has yet to prove a super form yet but spider x spider gets spiders and normals so spider het hypo x spider het hypo would also give you plain ol hets

Thanks I was thinking since there was two spiders there would be no norms...I wasnt thinkin last night lol. Well Im just goin to buy a Hypo female then =D

Assuming that there was only one allele for spider in each of your spider het hypo x spider het hypo, this is what you may predict from the offspring. Remember, you have two allelic traits, so you have to consider each contribution separately when doing your square.

Honeybees 3:16
Spider het hypo 6:16
Spider 3:16
Ghost (hypo) 1:16
Het hypo 2:16
normal 1:16

wow so you have a better chance at producing a honeybee when you breed a spider het hypo and a het hypo vs breeding a spider het hypo and a spider het hypo!!

I think not...

This tool is really useful
http://www.changbioscience.com/genetics/punnett.html

I will choose n for normal, s for spider and g for ghost gene

so a spider het ghost : sngn
a het ghost gn but since we want to use normal for spider allele : nngn

So the outcome :

Genotype Frequencies:
nngg: 2 ( 12.5% ) GHOST
nngn: 4 ( 25% ) Het Ghost
nnnn: 2 ( 12.5% ) Normal
nsgg: 2 ( 12.5% ) Spider Ghost (Honey Bee)
nsgn: 4 ( 25% ) Spider het ghost
nsnn: 2 ( 12.5% ) Spider



Let's do the same with spider het ghost x spider het ghost

nngg: 1 ( 6.25% ) Ghost
nngn: 2 ( 12.5% ) het Ghost
nnnn: 1 ( 6.25% ) Normal
nsgg: 2 ( 12.5% ) Spider Ghost (Honey Bee)
nsgn: 4 ( 25% ) Spider het Ghost
nsnn: 2 ( 12.5% ) Spider
ssgg: 1 ( 6.25% ) Super Spider Ghost
ssgn: 2 ( 12.5% ) Super Spider het Ghost
ssnn: 1 ( 6.25% ) Super Spider

The problems depends on what happens with super spider.

Do they exist ? Do they die in the eggs ?
If they die in the egg, then yes you have the same probability of getting Honey Bees.

If only 1 spider gene can be passed throw the egg, that mean you have more chance of getting Honey bees when breeding spider het ghost with spider het ghost.

Tadam !


Hope it's help a little bit

Thank you for the best explanation. I want to buy a hypo for my male spider het hypo to breed along with the female spider het hypo for my best chance to get a honeybee. Thanks everyone with the help

I think that since you want to express 2 traits, its a 4x4 punnet square. Meaning 8/16 (50%) of being a spider, 1/16 of normal, 2/16 het hypo, 1/16 hypo, and a 4/16 chance of being a hypo spider.

I might be completely wrong though :P

Edit: Someone beat me too it while I was figuring it out. XD
