Cytoplasmic genetic elements
WebCytoplasmic genetic elements are generally maternally inherited, although there are several exceptions where these are paternally, biparentally or doubly-uniparentally … Extrachromosomal DNA (abbreviated ecDNA) is any DNA that is found off the chromosomes, either inside or outside the nucleus of a cell. Most DNA in an individual genome is found in chromosomes contained in the nucleus. Multiple forms of extrachromosomal DNA exist, and, while some of these serve important biological functions, they can also play a role in diseases such as cancer. In prokaryotes, nonviral extrachromosomal DNA is primarily found in plasmids, whereas, in eukar…

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.
