How are genetics passed down

Genetics is the study of how heritable traits are transmitted from parents to offspring.When organisms reproduce, all the information for growth, survival, and reproduction for the next generation is found in the dna passed down from the parent generation.Research has indicated that genes may be passed down in different ways (modes of inheritance), which is another factor that could affect someone's genetic predisposition to.First is through a dominant gene—if you inherit a dominant gene you will develop that trait.A polymorphism alone will not lead to the development of a mental disorder.

It is also where the word achoo comes from, as this genetic trait is technically.They carry information that defines traits such as eye color and height.Mutations can be passed down to a child from his or her parents.Examples of genetic diseases passed from mother to son.But only women pass them down.

The first cell of a new human being forms during fertilization when an egg cell (from the mother) combines with a sperm cell (from the father).Scientists have concluded that while both parents are responsible for passing on good looks to daughters, only the mother passes on good looks to a son.These epigenetic marks can affect health and even the expression of the traits passed to children.Genetics helps explain what makes you unique, why family members look alike, and why some diseases run in families.Genes are passed down from a person's biological parents.

When we trace the paths of these qualities, we are following packages of information called genes.
