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 cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?
You want to select a bacterium that has obtained a genetic marker conferring resistance to tetracycline. How would you accomplish this?
What is 'Pharmaco-metabonomics'?
Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
Why does RNA have 5 bases and DNA has only 4?
WHAT IS Replicator theory?
Has vitamin c been produced in a human naturally before?
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?
what is pharmacogenomics?
How do u differentiate between Meiosis I & Meiosis II?
The gene for tallness (T) is dominant over the gene for shortness (t) in pea plants. A homozygous dominant pea plant is crossed with a heterozygous pea plant, and 200 seeds are produced. Approximately how many of these seeds can be expected to produce plants that are homozygous dominant?
what is Sickle Cell Anemia ?
