Answer:
True.
Step-by-step explanation:
For any two genes in any organism, the numerical value for the rembination frequency must be between 0% and 50%. Genes on separate (non-homologous) chromosomes have a recombination frequency of 50% and are "unlinked". Genes which are close together on the same chromosome have a recombination frequency near to 0% and are "tightly linked". So in this case since the recombination frequency is 0%, only AB and ab will be produced during meiosis.
