Question: Assume you have made a collection of mutant fruit flies that aredefective in various aspects of DNA repair. You test each mutantfor its hypersensitivity to three DNA-damaging agents: sunlight,methylnitrosourea (which cause alkation of guanosine),and nitrous acid (which causes deamination of cytosineand conversion to uracil which lead to a mutation and […]

1. For each replication of activity 13.1 in which you determine the type of gamete genotypes from a particular parent, write out the parental genotype followed by its gamete genotypes. 2. When allele A is dominant over allele A’, write out the parental phenotypes and genotypes. Then write out the […]

Q1. Which means of transport would most likely be used for moving a medium-sized molecule (like a monosaccharide or an amino acid) from a low concentration on the outside of a cell to a high concentration on the inside of a cell? Q2. Beaker A contains 25 percent salt solution. […]

The slug population has 2 alleles: slime1 (very slimy) and slime 2 (barely slimy). They arecodominant. The total population consists of 200 veryslimy slugs along with 400 barely slimy; there are also 400 slugswith medium sliminess. 1. Calculate the actual population’s genotype frequencies. 2. Calculate q and p for the […]
