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 antibodies that can bid to large parasites are IgE. IgE is a type of antibody synthesized by plasma cells and has only been found in mammals. If you have an allaergy, the immune system overeacts to an allergen by producing antibodies IgE. These antibodies travel to cells that release chemicals, causing an allergic reaction.
