MH,
what is the % of albinos would u get if u breed a albino with a 100% het?
Keep in mind that all % bases are estimated probability for EACH egg. When you breed a recessive trait (such as albino) with one parent (of either sex) being a homozygous )in this case a visual albino) with the other parent (of either sex) being heterozygous (visually aka phenotypically normal, yet has one allele with a mutant albino allele) each offspring has a 50% probability of being homozygous albino and a 50% chance of being heterozygous albino.
and if u breed 2 100% hets together?
Same as before except each egg (baby) has a 25% chance of being homozygous (albino) a 50% chance of being heterozygous, and a 25% chance of being normal. Since you can reduce the visually albino animals from the equation you can base your statistics off of the animals in question. This gives each non-albino offsring a probability of 66.6667% for being heterozygous and 33.333% probability of being genotypically normal.
and if you breed a tiger albino with just a supertiger no het will u get any albinos or will they all be just hets??
When you breed a recessive trait BOTH parents MUST have at least one of their two alleles mutated. For non-x-linked chromosomes you must get one chromosome from each parent... with dominant and incomplete dominant traits (like the tiger gene for instance) you would only require one chromosome for the mutation to be visual, thus the tiger which is the heterozygous phenotype (and genotype) of the Super Tiger trait which is the homozygous form. So since you have a visual albino it has BOTH chromosomes affected, and no matter which of those two it gives to its offspring ALL of the offspring will have one albino affected chromosome from that parent, making ALL of the offspring heterozygous for albino. For the tiger X super tiger crossing it works just like a het albino x albino. Each offspring will have a 50% chance of being a super tiger and a 50% chance of being a tiger. ALL of those will be 100% heterozygous for albino.
Hopefully that clears it up for you.
Take care,
Jordan
