The attached file contains results of an imaginary genetic experiment with a newly discovered species. These results provide genetic recombination evidence which will be used to determine which of four genes are found on the same chromosome (linked genes).
Pupils can be asked to perform a chi-squared analysis on the results.
G&T pupils can also use the recombination evidence to map the observed genes on the species two chromosomes.
A mark-scheme including working of the chi-squared analysis is provided.
The activity may also be suitable for G&T GCSE/IGCSE pupils following the separate science (triple award) route.
