Alabrador 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. to determine if sam is the father of the pups, which process could the breeder use?
a. pcr analysis
b. str analysis
c. mtdna analysis
d. y-chromosome analysis

The correct answer is option D, that is, Y-chromosome analysis.

Explanation:

One of the techniques for assessing the DNA that can be associated in a sense to examine male surnames is the Y-chromosome analysis. This process is a basic illustration of Y-chromosomes. A son gets a Y chromosome from his organic father and an X chromosome from his organic mother. On the other hand, a female would get an X chromosome from her organic mother, and the other X chromosome from her organic father.  

Thus, when the researchers examine Y chromosomes, they are examining the chromosomes, which are passed on with time via males in an ancestral line. The Y chromosome analysis has an important application for researchers who desire to examine the familial ties between the male members.  

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
