relatedness of organisms
, As described in class, which of the following best describes the goal of the procedure "replica
plating"? - Answers To identify mutants defective in growth control in yeast
As discussed in lecture, it is often easier to identify several mutants with a particular phenotype
than it is to figure out which of several mutants is likely the most important one to study. -
Answers True

mutants and identify particular mutants within that collection that have a specific phenotype.
Diploid - Answers Two sets of chromosomes for a given organisms, two copies of each
chromosome.
Mono-hybrid cross - Answers A cross between parents that differ in only one trait.
