Final answer:
False. With linked genes and some crossing over, recombinant progeny can be observed.
Step-by-step explanation:
False. With linked genes and some crossing over, recombinant progeny can be observed. When two genes are located close together on the same chromosome, they are more likely to be inherited together, leading to the production of nonparental types that result from recombination during meiosis. These nonparental types are the result of crossing over between homologous chromosomes, and they can occur with a frequency higher than 0% and lower than 50%, depending on the distance between the linked genes.
