Question

Which mutation(s) are in the same complementation group (alleles of the same gene) as mut 1?

ant breeders studying genes influencing leaf shape in the plant Arabiopsis thaliana identified six independent recessive mutations (mut1-mut6) that resulted in plants that had unusual leaves with serrated rather than smooth (wildtype) edges. The investigators performed the following crosses to sort these new alleles into complementation groups Which of the following pairs of alleles failed to complement each other? muti x mut2 = all smooth muti x mut3 = all serrated mut2 x mut6 all serrated mut1 x mut5all smooth mut5 x mut6 all smooth mut3 x mut4 = all serrated mut1 and mut2 mut1 and mut3 mut2 and mut6 mut1 and mut5 mut5 and mut6 mut3 and mut4

Explanation / Answer

The mutations are said to be in the same complementation group when they do not complement each other. Thus, the alleles of the same gene as mut1 is mut3. In other words, mut1 and mut3 are on the same gene.
