Question

50% recombinants in linked genes occur when ______.

पर्याय

• the genes are present on different chromosomes

• the genes are present far apart on the same chromosome

• the genes are present close together on the same chromosome

• the genes do not undergo crossing over

Answer 1

50% recombinants in linked genes occur when the genes are present far apart on the same chromosome.

Explanation:

Genes far apart on the same chromosome may show enough crossing over to produce 50% recombinants, appearing to assort independently. Closely linked genes produce fewer recombinants.
