Which of the following statements is not true of two genes that show $50 \%$ recombination frequency?
Which of the following statements is not true of two genes that show $50 \%$ recombination frequency?
the genes may be on different chromosomes
the genes are tightly linked
the genes show independent assortment
if the genes are present on the same chromosome, they undergo more than one crossovers in every meiosis
Solution
The tightly linked genes on chromosomes show $100 \%$ parental types and $0 \%$ recombinants. Two genes that undergo independent assortment indicated by a recombinant frequency of $50 \%$ are either on non- homologous chromosomes are located far apart in a single chromosome. As the distance between two genes increases, crossover frequency increases. More recombinant gametes, fever parental gametes.
