Extrachromosomal inheritance includes organelle inheritance,infectious inheritance,and maternal effectsthat is,anything transmitted through the cytosol.In infectious heredity,the infecting pathogen is cytoplasmic.What other non-Mendelian characteristic(s)must also occur?
A)infection of specific organelles
B)transfer of the pathogen's genes to the host nucleus
C)transfer of the pathogen's genes to the organelles
D)infection passing from maternal cytoplasm to egg cytoplasm
E)infection passing from maternal nucleus to egg nucleus

Question

Quizplus · Accepted Answer

Infectious inheritance in extrachromosomal inheritance involves the passage of the pathogen from maternal cytoplasm to the egg cytoplasm, hence option D is the correct choice. Option A (infection of specific organelles) and option C (transfer of pathogen's genes to organelles) are not necessary for infectious inheritance. Option B (transfer of pathogen's genes to host nucleus) and option E (infection passing from maternal nucleus to egg nucleus) are not relevant as infectious inheritance occurs through cytoplasmic transmission.
