Answer 3

genomic imprinting

Question 4

Heteroplasmy is associated with inheritance patterns involving

Answer 4

chloroplasts

Question 5

Answer 6

paternal leakage

Question 7

what organelles exhibit extranuclear inheritance

Answer 7

chloroplasts / mitochondria

Question 8

traits are inherited through genes not in the nucleus but are in the organelle genomes also known as cytoplasmic inheritance

Answer 8

extranuclear inheritance

Question 9

phenotypes controlled by imprinting genes follow non-mendalian inheritance offspring either maternally inherited or paternally inherited but NOT both
