Did you know?
WebIf the genes are not linked, the offspring will be 25% gray red, 25% gray purple, 25% black red, and 25% black purple. The percentages show that the genes are linked, and recombination frequency is 6%. A series of matings shows that the recombination frequency between the black-body gene and the gene for dumpy (shortened) wings is 36%. http://www.ib.bioninja.com.au/higher-level/topic-10-genetics-and-evolu/102-inheritance/chi-squared-test.html
WebSo how do you know if genes are linked? Linked genes occur when the ratio of parental vs. non-parental siblings are skewed.
