Which of the following statements about heteroplasmy is FALSE? The zygote inherits mitochondria from the egg. Mitochondria do not replicate before cell division. Mitochondria are distributed randomly in daughter cells following cell division. Cells differ in the proportion of mutated mitochondria, leading to phenotypic variation.
