Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.

dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
Gregor Mendel was able to determine traits by the ratio in which they appeared. For instance, he determined that a recessive trait will show up 25 percent of the time if one parent has it.
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
This would result in 1 heterozygous offspring. You can think of it like this: If the first parent is homozygous it would have AA alleles, the second heterozygous parent would be AB. When they mix genetically it would result in 4 combinations: AA, AA, AA, AB. As there is only one B there can only be one heterozygous offspring. This is not expected it is certain.

More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
1 out of every 4 the percent will be 25%

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 the phenotype is recessive then the genotype must be dd.

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.
dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
