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. which process could the breeder use to determine if sam is the father of the pups? pcr analysis str analysis mtdna analysis y-chromosome analysis

The question is asking to choose the following process could the breeder use to determine if Sam is the father of the pups and in my further research and in my own understanding, I would say that the answer would be Y-Chromosome Analysis. I hope you are satisfied with my answer and feel free to ask for more 

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
