______________________________________________________________ 1. People who carry a theoretical genetic disorder (called B-disease) can be identified from a 2kb DNA sequence. People who carry this genetic disorder have a single nucleotide polymorphism that results in a change of GTATCC to GGATCC, a site that only occurs once at nucleotide number 750 in this DNA sequence. Answer the following questions based on the information provided. (a) How can you develop a simple molecular test with enzyme BamH to identify the genetic disorder? ( (b) If you have carried out the molecular test (based on the information above) on a 100 individual and found that 24 were healthy (BB) and 26 were carriers (bb); 1) What is the ratio of heterozygous? 2) Show how can you identify the three types from the agarose gel

In mammals, albinism is caused by an autosomal allele that interferes with skin pigment. Early one morning on your way to genetics class, you observe that two normally pigmented javelina parents have an albino piglet. What are the genotypes of the parents? _________________________________ What is the probability that their next five offspring will be albino? __________________________ What is the probability that 3 of the next 7 offspring will be normally colored?______________________ Describe the process by which you would test these normally colored offspring to see if they carried the albinism gene. What are the expected ratios from that test? You want to develop a strain of albino javelina for commercial use (the other really white meat). Describe how you would go about developing that strain starting with the 2 parents and the one albino offspring.
