Question 4: Each parent would contribute one allele
Question 5: A white flower allele is presented in both homologous chromosomes (it would have to be in both because it is recessive)
It is further evidence for the theory of plate tectonics.
Hope this helps! :)
T cells
The immune response to a transplanted organ consists of both cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Although other cell types are also involved, the T cells are central in the rejection of grafts. The rejection reaction consists of the sensitization stage and the effector stage.
