How can a gene map be used? Why do scientists induce mutations in organisms?

Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome. Genome mapping provided a critical starting point for the Human Genome Project. Sequenced DNA fragments can be aligned to the genome map to aid with the assembly of the genome.

By inducing mutations, scientists have been able to increase genetic variation, which breeders depend on to produce crops with desirable traits, such as resistance to diseases and insects. ... Mutations can be induced in a variety of ways, such as by exposure to ultraviolet or ionizing radiation or chemical mutagens.

Explanation:

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
