The vestibulocochlear nerve mediates hearing and balance. Hearing can be assessed with a 512-Hz tuning fork. The Rinne and Weber tests are commonly used to assess for sensorineural and conductive deafness.
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>

Answer:
the trait with Mendelian inheritance shows segregation in the F2 generation.
Explanation:
Blending inheritance is the theory that the offspring inherits any characteristic that are intermediate between those of the parents.
However, Gregor Johann Mendel showed that this not true that hereditary substances from parents merge together in their offspring.
In the given question,
the offspring of true-breeding parents show an intermediate phenotype, although a trait such as flower color in snapdragons is determined by two alleles with incomplete dominance.
The difference is that the trait with Mendelian inheritance shows segregation in the F2 generation.
