Question
1.2
The A and P genes are unlinked. The A allele is dominant and results in red petals compared to the recessive a allele which results in pink petals. The P allele results in purple spots in the petals while the recessive p allele has no spots. A pink plant without spots is crossed to a red plant with blue spots. The progeny are 50% red with blue spots and 50% pink with red spots. What are the genotypes of the two parents?
A.
B.
C.

Question
1.3
The A and P genes are unlinked. The A allele is dominant and results in red petals compared to the recessive a allele that results in pink petals. The P allele results in purple spots in the petals while the recessive p allele has no spots. A pink plant with no spots is crossed to an unknown plant. The progeny are 25% red with blue spots, 25% red with no spots, 25% pink with blue spots, and 25% pink with no spots. What is the genotype of the unknown plant?

Question
1.4
The A and P genes are unlinked. The A allele is dominant and results in red petals compared to the recessive a allele that results in pink petals. The P allele results in purple spots in the petals while the recessive p allele has no spots.

Question
1.6
If an individual that has the dominant trait is crossed to an individual with the recessive phenotype, and all of the progeny have the dominant trait, what can be determined about the genotype of the parent with the dominant trait?
