The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
So the answer for (a) is basically the enzyme is breaking down the protein (which is the colored part) and this leaves the clear.
For the constants it would be the film and the temperature that the solution is at
For the final question, they could be improved by using more data and multiple trials
