Question

In general, crossing over occurs randomly along the chromosome and the further apart the genes, the more likely recombination will occur. True or False?

Answer 1

True. Crossing over occurs randomly along the chromosome, and the further apart the genes are, the more likely recombination will occur. Geneticists use the frequency of recombination as a measure of how far apart genes are on a chromosome.

Step-by-step explanation:

Answer:

True. In general, crossing over occurs randomly along the chromosome, and the further apart the genes are, the more likely recombination will occur.

This is because crossing over involves the exchange of genetic material between homologous chromosomes, and the likelihood of a crossover event increases with the physical distance between the genes.

Geneticists have used the frequency of recombination as a measure of how far apart genes are on a chromosome, allowing them to construct genetic maps of genes on chromosomes.
