Question

one map unit is equivalent to which of the following values?
○ the physical distance between two linked genes
○ the distance between a pair of homologous chromosomes
○ 1 nanometer of distance between two genes
○ 1% frequency of recombination between two genes

Explanation:

In genetics, a map unit (also known as a centimorgan) is defined as the distance between two genes that results in a 1% frequency of recombination. This is a fundamental concept in genetic mapping.

Answer:

1% frequency of recombination between two genes.
