Blue flower color is produced in a species of morning glories when dominant alleles are present at two gene loci, A and B. Purple flowers result when a dominant allele is present at only one of the two gene loci, A or B. Flowers are red when the plant is homozygous recessive for each gene. What flower color ratio is expected from the cross of aaBb to AABb?

The flower colour ratio obtained is:   Blue : Purple = 3 : 1.

Explanation:

                                                      aB                ab

                                          AB     AaBB           AaBb

                                                    (Blue)          (Blue)

                                          Ab     AaBb           Aabb

                                                    (Blue)          (Purple)

       Blue : Purple = 3 : 1.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
