Question: Which of the following statements is not true of two genes that show 50% recombination frequency?
Options:
A) the genes may be on different chromosomes
B) the genes are tightly linked
C) the genes show independent assortment
D) if the genes are present on the same chromosome, they undergo more than one crossovers in every meiosis
Show Answer
Answer:
Correct Answer: B
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.
