The yeast cells will replicate their chromosomes but will fail to complete cytokinesis.

Explanation:

Cytokinesis is a process in cell division where the cytoplasm of a parent divides into two daughter cells. It occurs in mitosis and meiosis.

Yeast proliferate asexually by budding which is a form of mitosis and has to under go all stages starting from interphase to telophase.

If a mutation in the CDC15 gene causes cell cycle arrest at telophase, it means proliferating yeast cells will replicate their chromosomes but they will fail to complete cytokinesis since it takes place at the telophase stage.
