Fro example, kernel color in wheat has been proposed to be controlled by at least two genes. In the model shown by the Punnett Square, two genes each have a dominant allele (A and B) and a recessive allele (a and b) Based on the model shown by the Punnett square, what determines kernel color

How does a lytic infection differ from a lysogenic infection?

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
