PLEASE HELP WITH THIS ONE QUESTION What statement about the inheritance of mitochondrial DNA is true?

A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.

B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.

C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.

D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.

Answers

Answer 1

Answer:

The answer should be C

Explanation:

The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.

The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.

The muscular system is made up of all the muscles which are present in the body, these help in connecting different body parts to the skeletal system. The nervous system consist of the brain and the spinal cord, this system is responsible for coordinating different functions in the body.

The endocrine system is responsible for secreting hormones which are responsible for the growth and development of body. The digestive system helps in absorbing the energy present in the food and distributing the energy. The circulatory system is responsible for the circulation of gases and different molecules across the body through blood vessels.
