The answer to this question is D
.
A control group is important to a controlled experiment because it is used in an experiment to establish its validity.
The allele for dwarfism - D its dominant
Recessive allele -d
If the person has heterozygous alleles -Dd the person will have achrondroplastic dwarfism
However if the person if homozygous for the allele DD it’s Lethal and person can’t survive
If both parents are Dd
Dd X. Dd
Offspring DD Dd Dd dd
Probability of children who survive with the trait have the genotype Dd
Probability - 1/4 + 1/4
Probability of having surviving children with the trait -1/2 -0.5
What Paul and Nancy should do to ensure a fair comparison between all the hives is to d<span>ocument the number of bees as compared to the amount of honey per hive.
This is the only fair comparison, because they will know approximately how much each of the groups produced compared to the number of bees.

Migration i think is the answer
