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.
Answer:
And so, an endothermic vertebrate is an animal that can produce its own heat and possesses a spinal backbone consisting of vertebrae. Examples of these organisms include most mammals (including humans), most birds, and some reptiles.
Explanation:
Ectothermic vertebrates are, for example, fish, amphibians and reptiles. Their temperature depends on the environment. The contrary to ectothermic are endothermic vertebrates, such as birds or mammals
