What are the benefits/risks when company traditional and genetically engineered breeding?
In sesame, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant over wrinkled leaf (l). The two characters are inherited independently. Determine the genotypes and phenotypes of the two plants which produce the following progeny: 318 one- pod normal, 98 one-pod wrinkled, 323 three-pod normal and 104 three-pod wrinkled.
What ethical dilemmas should be considered when genetic engineering is put into practice?
was math a subject in high school of difficulty for a person diagnosed with turner's syndrome?
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?
Why would farmers, doctors, and manufacturers be interested in Genetic Engineering?
What are the dangers of Genetically Engineered foods?
The ABO blood system has been employed to settle cases of disputed paternity. Suppose, as an expert in genetics, you are called to testify in a case where the mother is type A, the child is type O and the alleged father is type B. How would you respond to the following statements of the attornies: a. "Since the mother has type A, the type O of the child must have come from the father and since my client is type B, he obviously could not have fatered the child." Made by the attorney of the alleged father. b. "Further tests revealed that this man is heterozygous and therefore he must be the father." Made by the mother's attorney.

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 cats yellow is due to gene B and black to its allele b. These genes are located on the X chromosome (sex-linked). The heterozygous results in calico (tortoise shell). What kinds of offspring (sex & color) are expected from the cross: black male & calico female? Most calico males are sterile, why?
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?
