Question

How do you determine the order of genes on a chromosome?

Answer 1

Determination of order of genes:

1. The gene is the basic unit of heredity.
2. Genes are contained in chromosomes, which are some thread-like structures.
3. The order of genes on a chromosome can be determined by measuring the recombination frequencies.
4. By finding recombination frequencies for different gene pairs, we can do gene mapping that shows the order of the genes on the chromosome.
5. Determining the order of genes helps in estimating the relative distance between different genes present on a chromosome.
