Evidence Of Maternal Inheritance

See - Strickberger, M.W. 1968. Genetics. pgs 240-256.

Both maternal effects and maternal inheritance are identified by differences in reciprocal crosses. Extra chromosomal inheritance is due to non-nuclear genes. Maternal inheritance is due to extra-chromosomal inheritance and persists for many generations. Maternal effects typically are present only in the first generation of progeny. Maternal inheritance might be due to genes in the chloroplast or mitochondria organelles.

1. A difference in reciprocal crosses that are manifested for many generations.
2. The phenotype is determined by the maternal parent, regardless of the genotype of the individual.
