Homework SourseThe distance between the linked mutant alleles on a chromoso
The distance between the linked mutant alleles on a chromosome can be predicted with the resultant data. How?
| a) The lower the frequency of the offspring with the two mutant traits in F2, the closer the alleles are positioned on a chromosome. |
| b) The more viable the organism with the two mutant traits in F2, the closer the alleles are positioned on a chromosome. |
| c) The higher the frequency of the offspring with the two mutant traits in F2, the closer the alleles are positioned on a chromosome. |
| d) The less viable the organism with the two mutant traits in F2, the closer the alleles are positioned on a chromosome. |
Solution
The higher the frequency of the offspring with the two mutant traits in F2, the closer the alleies are positioned on a chromosomes.
A genetic map is based on frequencies of recombination and homologous chromosomes.The higher frequency of recombination with two genetic markers, the lower frequency of recombination with the markers, and smaller physical distance between them.
