WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene. WebUnlinked genes are genes that an organism carries on separate chromosomes. Not on homologous copies of the same chromosome. An example of a pair of unlinked genes in fruit flies ( Drosophila melanogaster) is. The gene for curly wings on chromosome 2, and. The gene for mahogany eyes on chromosome 3.

WebLinkage can be assessed by determining how often crossing-over occurs between two genes on the same chromosome. Genes on different (nonhomologous) chromosomes are not linked. They assort independently during meiosis, so they have a 50 percent chance of ending up in different gametes. WebGenes that are located on the same chromosome are called linked genes.
