True or false Why In a diploid plant genes A and B are close

True or false? Why?

In a diploid plant, genes A and B are closely linked. Single crossovers between these two genes occurs only in 10% of meiosis. Multiple crossovers are never observed. If an individual is heterozygous for both genes, then approximately 10% of its gametes are expected to be recombinant type.

Solution

Yes, it is true. Since Single crossover between gene A and B occurs only in 10% meiosis then always whenever they recombinent, only 10% of its gametes will show recombinents type.

Because no matter if the plant is homozygous for those gene A and B or heterozygous for the gene A and B, they always shows only 10% recombination in their gametes.
