In what way do segregational petite mutations differ from neutral petites?
A) Neutral petites are dominant and segregational petites are recessive mitochondrial genes. B) Segregational petites follow Mendelian inheritance as a result of the influence of nuclear genes; neutral petites, when crossed to wild type, produce only wild-type, normal-sized colonies. C) When a neutral petite is crossed to a segregational petite, all offspring are neutral petites. D) When a segregational petite is crossed to a wild-type cell, all offspring are petite. However, when a neutral petite is crossed to a wild-type cell, all offspring are wild type. E) Neutral petites follow Mendelian inheritance as a result of the influence of nuclear genes; segregational petites, when crossed to wild type, produce only wild-type, normal-sized colonies.
