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.

How are pedigrees a useful tool for understanding inheritance patterns Think of at least three ways they are beneficial?
Pedigrees are useful for understanding inheritance patterns because they visually represent family relationships and genetic traits across generations, making it easier to track how specific traits are passed down. They help identify carriers of genetic conditions, allowing for risk assessment in offspring. Additionally, pedigrees can reveal patterns of inheritance, such as autosomal dominant or recessive traits, which aids in predicting the likelihood of traits manifesting in future generations.
What was mendel typing to determine?
How traits are passed to offspring
How can heredity be observed?
Heredity can be observed through the passing down of traits from parents to offspring. This can be seen through similarities in physical characteristics, behaviors, and genetic disorders within families. By analyzing genetic markers and family pedigrees, scientists can further study and understand the inheritance of traits.
Can biology help you understand patterns of inheritance in your family?
Yes, biology can help you understand patterns of inheritance in your family by studying traits passed down through generations. By analyzing genetic information, you can determine the likelihood of certain traits or diseases being passed on to future generations based on principles of inheritance such as dominant or recessive genes.
Are traits passed from offspring to parents?
yup! they are passed through deoxyribonucleic acid also known as DNA. DNA is passed down through reproduction.

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
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)
When is gene pool is considered stable?
when the traits are dominant and are passed down to the offspring.
