WebA given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual. Alleles can sometimes result in different phenotypes (observable traits), with certain alleles being dominant (overriding the traits of other alleles) or, in some cases, multiple alleles acting in a codominant fashion.

Column 2 shows evidence of this process as a reduction in genetic diversity in this particular region of chromosome 2. Over time, the association between the beneficial allele and neutral markers breaks down as a result of the prink giftWeb2. Explain what is meant by the term ‘linked genes’ with respect to homologous recombination. For example, if an organism is heterozygous at two genetic loci on the same chromosome, in what way does the position of these alleles with respect to each other affect how they are transmitted to gametes during meiosis? the prink bomb

"WebIf we count up how many w copies are present, we find that there are five. The total number of gene copies in the whole population is 13 + 5 = 18 13+5 = 18. We can divide the number of copies of each allele by the total number of copies to get the allele frequency. " - How many alleles does a chromosome have
