Web16. Assuming three genes are linked, how many recombinant genotypes would you expect and at what frequency? six recombinant genotypes, less frequent than expected by chance. For a given cross, the expected number of double recombinants is 20 and the observed number of double recombinants is 15. What is the coefficient of coincidence (c)? WebHaving multiple alleles is (usually§) a consequence of multiple different sequence variants for a gene (i.e. genetic polymorphisms) being present in a population. However, any …

Genes on separate chromosomes are never linked (center). … 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.
