Final answer:
Recombinants are explained through Morgan's experiments on genetic linkage and recombination. Linked genes can become unlinked through homologous recombination during meiosis, resulting in the formation of recombinant offspring with new allele combinations. Recombination frequencies can help determine the relative positions and distances between genes on a chromosome.
Step-by-step explanation:
Recombinants are explained through Morgan's experiments on genetic linkage and recombination. Linkage occurs when genes are located on the same chromosome and tend to be inherited together.
However, Morgan's research showed that linked genes can sometimes become unlinked through a process called homologous recombination during meiosis.
This results in the formation of recombinant offspring with new allele combinations. The frequency of recombination allows scientists to infer the relative positions and distances between genes on a chromosome.
