If you crossed a black hen/roo with a white hen/roo, the offspring would NOT be blue.
If he was recessive white, the chicks would be black.
If he was dominant white, the chicks would be white with some black "smudges" or "spots".
The only way to produce 100% blue chicks is to cross a black roo over splash hens or a splash rooster over black hens.
A test cross between a homozygous recessive and a heterozygous individual will yield 50% of offspring as homozygous recessive. This is because all the offspring will inherit one recessive allele from the homozygous recessive parent.
A cross between two homozygous parents will form a 100 percent chance of a heterozygous offspring. One homozygous parent must have the dominant allele, and the other must have the recessive allele. So, if the circumstances are correct, these characteristics will make for a 100 percent chance of a heterozygous offspring.
A. Offspring with heterozygous genotype 100 percent B. Offspring with homozygous dominant genotype 0 percent C. Offspring with at least one copy of recessive gene 50 percent
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
If one parent is homozygous recessive for a trait, all of their offspring will inherit one copy of the recessive allele. Therefore, 100% of the offspring will inherit the recessive allele from a homozygous recessive parent.

false
100% is not probable, it is definite
good stuff
A. Offspring with heterozygous genotype 100 percent B. Offspring with homozygous dominant genotype 0 percent C. Offspring with at least one copy of recessive gene 50 percent
50 percent
You think probable to percent error.
Very probable not more than 0,2 %.
