Which sample is from the father of the calf? Explain your answer.

 

Lane 3 male s the father of the calf because it shares 3 bands in common with the calf and the mother.  

 

 How many bands does the calf have in common with its mother?

 How many bands does the calf have in common with its father? 

Propose a plausible explanation for the number of bands from each parent.

 

 

The calf shares 3 bands in common with both the mother and the father. Each parent shared 50% of its DNA with the calf therefore each parent has 3 bands in common with the calf.

 

 

 After adding the probe and filter, what additional information have you learned about the genotype of the calf?

 

 

The calf is a homozygous genotype with the father calf.  

 

 

 Given that the probe pairs with a specific DNA strand in the matrix, what can you conclude about the nucleotide

 sequence of the Baby’s DNA fragment that pairs with the probe sequence?  

 

 Discuss reasons that it might be useful to find out whether a newborn carries a specific gene or allele.
