Linkage between a gene of interest and a DNA marker is being studied. A mating results in 6 parental and 3 recombinant offspring

-The results of this mating are sufficient to conclude with confidence that the gene of interest and the DNA marker are linked.

Quizplus · Accepted Answer

With only 9 offspring, the sample size is too small to confidently conclude linkage between the gene of interest and the DNA marker. Generally, a larger sample size is needed to accurately determine genetic linkage, as it provides more statistical power to detect a true linkage versus random assortment.
