How do pedigrees help us understand how traits are passed down?

Pedigrees help us understand how traits are passed because they are specfically bred to have a certain trait(s). This is usu. done by breeding two animals that look alike and breding their offspring to another look-alike animal/creature. Note that some pedigrees are "ruined" due to inbreeding (incest) resulting in occasional deformities or flaws.
Example
A purebred german shepherd should have two black moles on his/her cheeks together. If you bred two similar dogs you should have similar puppies. If you take another dog such as a traditional black and white border collie and bred it to a german shepherd, you can see how the puppies appear and what the differences are.
SOme traits are more desirable than others and offspring will be bred with another animal with desired traits. If this fails, normally the resulted offspring will be bred to the same creature or one similar to try and get the result. This is a result of what genes are reccesvie and which are dominate. The mroe you bred for something specific the more likely a gene is to become dominate.

Are traits passed from offspring to parents?
yup! they are passed through deoxyribonucleic acid also known as DNA. DNA is passed down through reproduction.
What is the physical characteristics of an organism that is passed down?
double and single eyelid,having blood disorder The answer to this question is heredity which has to do with genetics.
What are heritable traits?
The word inherited means that it is passed down through the genes from parent to child.
Why can't acquired traits be passed down?
As they are environmental changes, like a sun tan or scars.
What do gregor mendels peas have to do with the study of heredity?
The peas had passed traits down like red or white and short or tall.
How do geneticsists use pedigrees?
To help them see how genes are passed down from families, basically for co-dominance and such, and family heredity.
What is it that is passed down from one generation to another?
Genes or traits
When is gene pool is considered stable?
when the traits are dominant and are passed down to the offspring.

What are some visible traits inherited by humans?
Characteristics passed down by parents to the offspring.
What must be true of traits that are passed down through generations?
Traits that are passed down through the generations must be either culturally or environmentally inculcated or genetically inherited (or some combination of these). Evolutionary biology concerns itself with genetically inherited traits. In the long term, for genetically inherited traits to continue to be passed down through the generations, they must be at least neutral with regard to reproductive fitness, or advantageous (i.e. they must not be subject to negative selection pressure)

Why are stronger traits passed down to offspring?
So that the offspring have a better chance of survival. these traits are often chosen through natural selection.
How and when did humans know the traits are inherited from their parents?
Put simply, inherited traits are those passed down by your parents and are found in your genes e.g. big nose, big ears, little feet. Aquired Traits are traits that are not passed down but instead "aquired" since birth. An example of this is: scars, pierced ears, the length of your hair, the loss of a limb.
