Q1. Michael Lynch and John Conery showed that there is a strong negative correlation between Ne? and genome size. How would you interpret this relationship? How can Ne? be estimated without independently measuring an effective population size and the mutation rate for all the species in their analysis? Q2. Most […]

Generally, aneuploidies are caused by the impaired assortment of chromosomes during meiosis. For example, they are caused when the homologous chromosomes of pair 21 do not separate and, therefore, gametes with two chromosomes 21 and gametes without chromosomes 21 are formed. If a gamete with two chromosomes 21 fertilizes a […]

The genes for mahogany eyes and ebony body are approximately 25 map units apart on chromosome 3 in Drosophila. Assume that a mahogany-eyed female was mated to an ebony- bodied male and that the resulting F1 phenotypically wild-type females were mated to mahogany, ebony males. Of 1000 offspring, what would […]

An investigator purified a protein (protein X) from E.Coli. Sheinjected protein X into rabbits to generate antibodies thatrecognize and bind to protein X. Using an electrophoretictechnique, she separated the proteins from a crude cell extract andused the antibody to locate protein X on the gel. TO her surprise,the antibody bound […]
