Extranuclear genes show a biparental inheritance patter in yeast since
A)progeny from diploid vegitative growth can have the phenotype of the dominant phenotype.
B)progeny from diploid vegitative growth can have the phenotype of the $\alpha$ parent.
C)progeny from diploid vegitative growth can have the phenotype of only the a parent.
D)progeny from diploid vegitative growth can have the phenotype of either the a or the $\alpha$ parent.

Question

Quizplus · Accepted Answer

Extranuclear genes, also known as cytoplasmic genes, are inherited through the cytoplasm rather than the nucleus. In yeast, they are inherited biparentally, meaning they can come from either the a or the F1F1F1S1F1F1F10 parent. Therefore, progeny from diploid vegetative growth can have the phenotype of either parent. Option A is incorrect because it implies that one parent's phenotype is always dominant, which is not necessarily true. Option B is incorrect because it describes a specific genotype, which may or may not be relevant to the question. Option C is incorrect because it suggests that only one parent contributes to the progeny's phenotype, which is not the case for extranuclear genes.
