Answer:
3.5 percent (3.5%)
Explanation:
In genetics, <em>crossing over</em> or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/<em>loci</em> located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/<em>loci</em> (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
