Cytoplasmic segregation vs induction
WebCytoplasmic inheritance meaning is the inheritance of organelle DNA in the offspring from the parent’s DNA. Cytoplasmic inheritance is different from nuclear genetics because it does not follow the laws of gene inheritance. Half of the genes will come from male and female parents according to gene inheritance. However, depending on the ...
