The smallest living thing in the list is a bacteria. Bacteria are single-celled organisms that are smaller than a frog embryo and mitochondria. Viruses are not considered living organisms because they cannot replicate on their own, and an atom is a non-living, indivisible unit of matter.
The mitochondria in the egg contain their own DNA, separate from the cell's nuclear DNA. This mitochondrial DNA can affect the development of the cloned embryo. If the cloned embryo contains donor egg mitochondria, it may lead to mitochondrial diseases and complications in the embryo, making human cloning more difficult.
An egg contributes the majority of the genetic material needed for the embryo to develop, including the mitochondria for energy production. In contrast, a sperm cell provides only half of the genetic material necessary for embryo formation.
An egg contributes the majority of the genetic material (chromosomes) needed for the embryo, as well as organelles like mitochondria for energy production. Sperm only provides genetic material.
A sperm cell contributes half of the genetic material needed for the embryo, including the father's DNA. Additionally, the sperm cell's mitochondria are typically discarded during fertilization, so the embryo mainly relies on the egg cell for its cellular organelles.
An embryo is the early stage of development of a multicellular organism. In humans, the embryo is formed during the first eight weeks of gestation following fertilization of an egg by sperm. The embryo undergoes rapid cell division and differentiation to form the basic structures of the body.

Mitochondria are inherited from the mother through the egg cell. When a sperm fertilizes an egg, the sperm's mitochondria are typically destroyed, so the mitochondria in the resulting embryo come exclusively from the mother.
No, the egg does not destroy the sperm's mitochondria. During fertilization, the sperm cell's mitochondria are typically destroyed, as the egg provides the necessary energy-producing organelles for the developing embryo.

The heart is the second organ to develop in the embryo, following the development of the neural tube. It starts to form and beat by about the third week of gestation.
The egg cell contributes half of the genetic material (DNA) needed to create a new organism. It also provides organelles, such as mitochondria, that are essential for cellular functions in the developing embryo. Lastly, the egg cell plays a role in initiating cell division and guiding the early development of the embryo.
Mitochondrial DNA is passed down from the mother to her offspring. This type of DNA is found in the mitochondria, which are structures found outside of the cell nucleus. Mitochondrial DNA is inherited exclusively from the mother because only the egg cell contributes mitochondria to the developing embryo.
