Q613
A pair of genes are linked if their recombination frequency in test cross is
A.
50%
B.
75%
C.
100%
D.
Less than 50%
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
A pair of genes are linked if their recombination frequency in the test cross is Less than 50%.If the genes are far apart on a chromosome or different chromosomes, the recombination frequency is 50%.
In this case, the inheritance of alleles at the two loci is independent. If the recombination frequency is less than 50% we say the two loci are linked.
