What are the benefits/risks when company traditional and genetically engineered breeding?
Is Genetic engineering the best of solution?
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?
7) Diabetes is recessive. A) If woman has diabetes and marries a man that doesn’t have it, is it possible for their offspring to acquire this disease? A A Aa Aa Aa Aa a a genotypes Phenotype 100% Aa, Heterozygous 100% No diabetes B) If none of the father’s ancestors had ever had diabetes, would their children have a chage of getting the disease? Explain
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?
Can you name a few potential risks of Genetic Engineering?

Differentiate between biotechnology and bioengineering?
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?
