WebMar 30, 2024 · Cytoplasmic male sterility (CMS) is a complex phenomenon in plants, rendering them unable to produce functional pollen. In general, this is caused by an abnormal or dysfunctional mitochondrial genome.

WebUsing pedigrees, distinguish between dominant, recessive, autosomal, X-linked, and cytoplasmic modes of inheritance. Predict the transmission of phenotypes associated with maternal effect genes. Explain why the terms “dominant” and “recessive” are context dependent and may differ at the cellular level or at the level of a pedigree. WebApr 22, 1992 · This paper shows that the cytoplasmic genetic system would be expected to evolve towards uniparental inheritance, given the existence of deleterious symbionts capable of invading the host cytoplasm together with nuclear genes that lead to the elimination of cytoplasmic elements from one of the gamete types.
