A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
Genetic engineering harms or benefits human societyharms? What obstacles must gene therapy overcome? What instrumentation is required for DNA sequence analysis and how does it work?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child?
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?
How is Genetic Engineering currently used?
What are the differences between Genetic Engineering and breeding?
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?
cancer cells have their dna wound back wards, is that true?
Why do we age?
our hair comes from our mother's father.Is it true or not?
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?
what are the genetical reasons behind obesity?
What is Heterozygote detection?
In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino?
Explain in terms of gene product function how a mutant allele can be dominant? recessive?
