Cytoplasmic inheritance refers to the transmission of genetic material that is not present in the nucleus. but is in the cytoplasm. This type of inheritance typically involves genes found in organelles, such as mitochondria (in animals) or chloroplasts (in plants). These contain their own DNA and are therefore able to transmit genetic information independent of the nuclear genome.

Key points regarding cytoplasmic inheritance:

Maternal inheritance: in most cases Cytoplasmic inheritance follows the maternal pattern. This is because the egg cell contributes most of its cytoplasm to the zygote. As sperm makes little or no contribution, mitochondrial DNA is usually inherited from the mother.

Mitochondrial DNA: In humans and other organisms, mitochondria are the best-known organelles involved in the inheritance of cytoplasmic DNA. Mitochondrial DNA (mtDNA) can cause mutations that can result in inherited diseases.

Chloroplast DNA: Chloroplasts in plants are responsible for photosynthesis and contain their own DNA. Chloroplast DNA is inherited maternally in many species. Although in some plants genetics can be inherited paternally or biparentally.

Non-Mendelian Inheritance: This is because cytoplasmic inheritance does not follow Mendelian laws of inheritance. (which is based on nuclear genes) is therefore considered a form of non-Mendelian inheritance...
