Answer:
a. F1 genotype PpBb
b. F1 phenotype All black offsprings
c. F2 phenotypic ratio: Black 9/16 cream 3/16 albino 4/16
Explanation:
In rats, the allele for pigmentation (P) is dominant to the allele for albinism (p).
The B gene allele for black pigmentation (B) is dominant to the allele for cream pigmentation (b).

The answer to the question is letter C which is A supercell storm occurs only during the winter months. The statement is false since supercell storms can occur during any season may it be summer or spring. Hope I did help you.
The given question is incomplete as the detail of the population was not given, however, the correct diagram related with the question is attached with the answer:
Answer:
The correct answer is -
brown alleles
8
20
0.4
0.6
Explanation:
1. To calculate the frequency of the brown allele, count the number of BROWN ALLELES and divide by the total number of alleles in this population
2. In this beetle population, the number of brown alleles = 8 represented by genes with the black color segment.
3. In this beetle population, the total number of alleles for both colors = 20
4. The frequency of the brown allele in this beetle population = 0.4
5. The frequency of the green allele in this beetle population = 0.6
You have a 25% chance of having a tall plant that carries the recessive gene of being short.
