In drosophila, an autosomal recessive mutation sepia (se) (on chromosome 3) causes sepia eye door, and another recessive mutation scarlet (st), also on chromosome 3, causes scarlet eye color. distance between the two genes is 18 map units apart. flies which are recessive homozygous by both of these mutations have […]

when chicken egg whites( which are chiefly composed of proteins) are heated they harden although we cannot reverse this process, we can dissolve the hardened egg white if we heat it in a solution containing a strong detergent ( eg sodium dodecly sulfate) and a reducing agent such as B- […]

In interrupted mating experiments using an Hfr strain in E. coli, you find that two genes, bio and arg, are transferred at about the same time. A third gene, pab is transferred slightly later. In order to determine the gene order, you mate an Hfr strain that is pab+ bio+ […]
