Question

Cytoplasmic inheritance is also called maternal inheritance because it is?

• A. Without sexual reproduction
• B. Only female parent takes part in multiplication
• C. Most of the cytoplasm of the zygote is provided by ovum
• D. All the above

Answer 1

The correct option is C Most of the cytoplasm of the zygote is provided by ovum

Cytoplasmic inheritance is the transmission of genes that occur outside the nucleus. It is found in most eukaryotes and is commonly known to occur in cytoplasmic organelles such as mitochondria and chloroplasts. Mitochondrial diseases are inherited from the mother, not from the father: mitochondria with their mitochondrial DNA from the mother's egg cell are incorporated into the zygote and passed to daughter cells, whereas those from the sperm are not.

So, the correct answer is 'Most of the cytoplasm of the zygote is provided by ovum'
