Arnoldo is a botanist studying inheritance in flowers. When he crosses pure breeding red carnations with pure breeding white carnations, the offspring in the F 1 generation have pink flowers. In the F 2 generation, some flowers are red, some flowers are white, and some flowers are pink. When he crosses blue poppies with yellow poppies, all the offspring in the F 1 generation have both blue and yellow petals. In the F 2 generation, some have only blue petals, some have only yellow petals and some have both yellow and blue petals. Which of the following correctly identifies the inheritance patterns Arnoldo is observing?
Flower color in the poppies is polygenic, while flower color in the carnations is controlled by multiple alleles.

Flower color in the carnations is polygenic, while flower color in the poppies is controlled by multiple alleles.

The red allele is incompletely dominant over the white allele in the carnations, while the yellow and blue alleles in the poppies are codominant.

The yellow allele is incompletely dominant over the blue allele in the poppies, while the red and white alleles in the carnations are codominant.
