Question
Identify each of the following statements as TRUE or FALSE (and do not forget to explain your reasoning). Each statement refers to two heterozygous loci in the same genome.
a. The maximum expectation for frequency of recombinant genotypes produced in meiosis cannot exceed 0.5.
If the two loci are on the same chromosome, the maximum expectation for the number of physical crossover events between them cannot exceed 0.5.
If the loci are on different chromosomes, the observed recombination frequency will be 0.
Explanation / Answer
a.
The given statement is true.
When two genes are located on different chromosomes or when they are widely separated on the same chromosome, the recombination frequency will be 50% or 0.5. This is a consequence of independent assortment.
Hence, the given statement is false.
When two genes are located on different chromosomes the recombination frequency will be 50% or 0.5. This is a consequence of independent assortment.
Hence, the given statement is false.
