What are the dangers of Genetically Engineered foods?
Is There any way in which a currently living could be mutated in reality to such a large scale as to which others could see the mutation, such as a third arm?
What situations might be viewed as ethical uses of human cloning? Are you doubtful, fearful, or hopeful about human cloning?
what are introns and exons?
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
In a cross AABBCC and aabbcc (P generation), what would be the frequency of AAbbCc in the F2 (assuming no linkage)?
What does it mean to say that an allele is pleiotropic?
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 the role of Beta-lactamase in Gene Cloning ?
How can cloning help or hurt farmers?
The weight of the fruit of one variety of squashes is determined by three pairs of genes: AABBCC produces 6 lb squashes and aabbcc produces 3 lb squashes. Each dominant allele adds 1/2 lb tothe base weight (3 lb). If a pure breeding line that produced 6 lb squashes was crossed with a pure breeding line that produced 3 lb squashes, what would be the phenotypic ratio of the F1 and the F2?
which chemical substance is generally used to obtain polyploids?
