As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.

Reptile [31]
PP-  purple homozygote
pp- white homozygote
Pp- purple hetrozygote

If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)

Now, if those offsprings cross with each other: Pp x Pp
results:
  1/4 would be purple  homozygote -> PP
  1/4 would be white -> pp
  2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
