With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.

 

 

Why is it that some people show two bands?

A man with type A blood group marries a woman with type A blood group. Their first child has type O blood. What is the genotype of the Man, proportion of his gametes are expected to contain the IA allele, and probability that their next child will have type A blood respectively:

Parents that are homozygous for different mutations a, b and c are crossed, producing offspring that are heterozygous as following

aa X bb        =  ab  (X)          

 bb X cc         =  bc  (Y)

aa X cc          =   ac  (Z)

If a and b belong to same locus but b and c belong to different locus then phenotype of heterozygote

Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement the second, third and fourth mutant lines. However, no other complementation groups do the four mutant lines belongs to?
