The true breeding genotype is important in genetic inheritance because it ensures that offspring will inherit specific traits from their parents consistently. This genotype is homozygous for a particular trait, meaning that all offspring will also exhibit that trait. This predictability is crucial for understanding and studying genetic inheritance patterns.
It depends on the parents' genes. If both parent have a Pp genotype, then the offspring has a 25% chance of having a PP genotype. But if both parents have a PP genotype then its 100%.
The parents' genotype is made up of the combination of alleles they inherit from their own parents. These alleles determine the genetic characteristics and traits that the parents can pass on to their offspring. Each parent contributes one allele for each gene, resulting in the genotype of the offspring.
In the cross BB x bb, all offspring in the F1 generation will have the genotype Bb, as they inherit one allele from each parent. None of the offspring will have the same genotype as either parent.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.

What fraction of the offspring of parents each with the genotype KkLlMm will be KKLlMm?

If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
The alleles that are passed from parents to offspring
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.

Offspring of true-breeding parents are called F2 generation. This is often seen in hybrid breeding programs when they are working to produce a certain trait.
That depends entirely on the genotypes of the parents.
