In case of Cms-T, plasmid-like event in the mitochondria is absent but some unique polypeptides are produced in the mitochondria which bring the male sterility.
Cytoplasmic mutation from male sterile to male fertile; ii. Read more: Article written by- Tasneem Gandhi Article reviewed by- Tushar Chauhan This article is written by our dearest friend Tasneem Gandhi on special request of team genetic education.
It indicates that homozygous either KK or kk strains become heterozygous following an exchange of K and k genes without cytoplasmic exchange.
Mutation rates of mitochondria are much greater than that of nuclear DNA allowing mitochondria to evolve more rapidly than nuclear genes. In this fungi, sexual reproduction takes place by the fusion of two somatic cells to form a diploid zygote nucleus.
Because mitochondria are organelles that contain their own genome, they follow an inheritance pattern different from simple Mendelian inheritance, known as extranuclear or cytoplasmic inheritance. Appearance of the typical 3: 1 ratio in F3 in place of F2.
