Question

A Labrador retriever breeder needs to determine if three male pups who were born to Sadie, his black Labrador retriever, are the offspring of Sam, a yellow Labrador retriever from another breeder. Which process could the breeder use to determine if Sam is the father of the pups?

Answer 1

The breeder can use DNA testing to determine if Sam is the father of the Labrador retriever pups.

Step-by-step explanation:

In order to determine if Sam is the father of the Labrador retriever pups, the breeder can use DNA testing. DNA testing can compare the genetic material of the pups with the genetic material of Sam to establish paternity. This can be done by analyzing specific regions of DNA called markers, which are unique to each individual. By comparing the markers of the pups and Sam, the breeder can determine if Sam is indeed the father.

Answer 2

Answer: The things we know are:

Sadie, the mother, is a black labrador.

Sam, the possible father, is a yellow labrador.

Discarding things such as a scientific indagation, the breeder could look for traits in the pups.

For example, yellow is recessive against black, so if the pups are yellow, there is probable that the father is Sam, none the less, if the pups are black there is also the possibility where Sam is the father, just in this case the color genes that the pups received are the ones of the mother.

A good starting point is looking at the color, the posture, and things like that.

In the end, these things are only statistics, there is not any determination here, the only real (scientific) determinative process is a paternity test.
