Extranuclear inheritance is a consequence of the presence of genes in:
1 ER and mitochondria
2 lysosomes and ribosomes
3 ribosomes and chloroplast
4 mitochondria and chloroplasts
Explanation:
Exp:D Extra nuclear inheritance is a consequence of the presence of genes in mitochondria and chloroplast. These organelles have their own DNA, which is separate from the DNA in the nucleus. The genes in mitochondria and chloroplasts are responsible for a variety of cellular functions, including energy production, photosynthesis and cell signaling. These organelles are regarded as semi-autonomous organelle.

Which part of the sperm has the aggregation of Golgi bodies?
1 Middle piece
2 Tail
3 Axial filament
4 Acrosome
Explanation:
Exp:D During sperm formation Golgi apparatus forms the acrosome. Acrosome contain a number of hydrolytic enzyme which helps in penetration of egg's coat through sperm.

Maternal inheritance is due to the genes present in :
1 lysosome
2 nucleoplasm
3 nucleus
4 mitochondria
Explanation:
Exp:D Maternal inheritance is due to the genes present in mitochondria. It is generally observed in many eukaryotes. Nucleoplasm It is a clear fluid medium in which all the contents of the nucleus are embedded. Lysosome It is membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids. Nucleus It is membrane-enclosed organelle within a cell that contains the chromosomes.
