The specific restriction enzyme help to cut out the specific
gene.
And DNA probe help to detect the pesence or absence of desired
DNA.

A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?

The village of Oblong has 400 normally-shaped residents. Transferrin is an iron carrier found in blood, and electrophoretic variation of this protein is determined by an autosomal codominant system. The citizens of Oblong were typed for their transferrin complements. The distribution of transferrin phenotypes was: 100 CC, 100 CD, and 200 DD. What is the frequency of the C allele?

In mice colored coat is dominant to albinism. Sniffles, a male mouse with a colored coat is mated to Esmeralda, an alluring albino. The resulting litter of six young all had colored fur. The next time around Esmeralda was mated with Whiskers, who was the same color as Sniffles; some of this litter were white. a)What are the probable genotypes of Sniffles, Esmeralda, and Whiskers? b) If a male of the 1st litterwas mated to a colored female of the 2nd litter, what phenotypic ratio might be expected among the offspring? c)What would be the expected results if a male of the 1st litter was mated to an albino from the 2nd?

Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
