Answer:
Choice A, BCAD
Explanation:
Recombination frequency is a number that describes the proportion of recombinant offspring produced in a cross. In other words, it tells us how often does crossing over happen between the loci of two observed genes. The bigger the RF is, the larger is the distance between two genes. That means that genes B and D (RF 14%) are the most distant ones, and all the others are located inbetween them. You have to sketch the order of genes based on how far away they are from each other.

If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.
With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.
With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.
With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>
