WebAnswer (1 of 10): The standard way to detect linkage is to perform a test cross with a double heterozygote. If the genes are not linked, you would expect a 1:1:1:1 phenotypic ratio in the offspring. Any significant deviation from this ratio suggests linkage of the two genes. If you produced an F... Webinvolving sex-linked traits. 36 Objective 23 Other traits, besides sex, are controlled by genes on the sex chromosomes. These are called sex-linked traits. Traits controlled by the X are X-linked. Traits controlled by the Y are Y-linked. Since most sex-linked traits are controlled by the X, you can assume X-linkage, unless it says Y-linked. designer brands discount pricesWebUnlinked Genes. Unlinked genes appear to segregate and show independent assortment. There will be a random and even distribution of gamete types, and an RF of 0.50 is the expectation.
