As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
<h3>What is Genetic material?</h3>
Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.
In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.
These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.
Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

Answer:
a. 1 : 1
b. 1 : 1
Explanation:
In this case, a heterozygous tall plant (Ty) is crossed with a homozygous short plant (yy) - which we can deduce as the recessive alleles only exhibit themselves in the absence of the dominant alleles.
The resulting offspring would have the genotypes (refer to attached image):
Ty (Tall)
Ty (Tall)
yy (short)
yy (short)
The genotypic ratio would be - 1:1 (Ty & yy are the genotypes present)
and the phenotypic ratio would be - 1:1 (tall and short are the phenotypes present)
