In sweet pea, red flower color is controlled by two genes involved in the anthocyanin pathway, A and B. Both genes are required for expression, so that a recessive pair of alleles at either locus would result in a pink phenotype. If an AaBb plant were allowed to self-cross and you got only red and pink flowers, what dihybrid ratio would you expect in the offspring?

The dihybrid ratio we expect in the offspring is 9:7.

Explanation:

This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.

So in this case of  complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

the answer is cell division : )
