Chloroplast inheritance
WebChapter 9 – Extranuclear Inheritance Chapter 9 Concepts Extranuclear inheritance occurs when phenotypes result from genetic influence other than the biparental transmission of genes located on chromosomes housed within the nucleus. Organelle heredity, an example of extranuclear inheritance, is due to the transmission of genetic information contained … WebExtranuclear inheritance, including mitochondrial and chloroplast inheritance, occurs in eukaryotes when genetic information is transmitted by means other than through nuclear DNA. Select the examples of mitochondrial or chloroplast inheritance. Commercial banana plants produce seedless fruits because the plants are triploid. Narow, slit-like ...

Corn … WebChloroplasts may have circular or linear DNA molecule of genomic size ranging from 120 to 400 kb controlling the synthesis of specific RNA and protein molecules. Several genes were reported to be located on chloroplast genome and genetic maps have been prepared in Chlamydomonas, maize etc. Cytoplasmic Organellar Inheritance: Type # 2.
Webchloroplasts. In addition to these cases of non endelian inheritance, some characters in several organisms M exhibit a Mendelian inheritance pattern but the development of these characters in an individual is markedly affected by the genotype of the maternal parent of the concerned individual; such cases are classified as maternal effects.
WebJul 9, 2024 · The inheritance of chloroplast genome DNA (cpDNA) differs from that of the nuclear genome. The cpDNAs of most species originate from the female parent, whereas some plastids are paternal or biparental in origin. The plastid transmission of Pinaceae species is thought to occur exclusively by paternal inheritance with a few exceptions. … WebMar 21, 2024 · PDF Pea has been hitherto considered to have strict maternal inheritance of mitochondria, as most of flowering plants.
