A cabbage farmer is trying to selectively breed his crop for larger heads of cabbage Currently, the average weight of a head of cabbage in his field is 2.5 kg. He selects the plants producing the largest heads as breeders, the average size among this proportion of his population is 5.5 kg. In the next generation, the average weight of a head of cabbage in his field is 3.5 kg a. Calculate heritability for this trait. b In part a, did you calculate narrow-sense or broad-sense heritability? C. If the farmer wanted to increase the average weight of a head of cabbage to 5 kg (assume the change must occur within one generation) from an initial population mean of 2.5 kg, how much must the average head among the breeders weigh?

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.
