Answer: If the F2 occurs in the ratio 9 blue:3 pink:4 white, one gene pair (i.e 2 genes) control the flower color phenotype.
Explanation: This principle is called INCOMPLETE DOMINANCE where one gene (dominant) won't completely override the other (recessive).
Let assume B represents the dominant gene and b represents the reccesive gene. Let also assume that Blue color is dominant over white color. We can assign the genotype as follows;
Homozygous dominant genes BB will produce Blue color
Homozygous recessive genes bb will produce white color
Heterozygous genes Bb will produce pink color.
Therefore, a pair of gene ( 2 genes) will determine the flower color phenotype.
The australian mammal spends most of its life in trees is the koala, Koalas survive on a diet of eucalyptus leaves and can eat up to a kilogram a day.
<h3>What are the mammals?</h3>
Mammals are a group of animals (vertebrates) that have backbones and hair or fur.
They are warm-blooded (endothermic), and they have four-chambered hearts.
They also feed their young with milk from the mother's body. The young of most mammals are born alive.
Thus, The australian mammal spends most of its life in trees is the koala.

It would be found at the bottom of the layers.
Explanation:
