With modern molecular methods it is now possible to examine variants in dna sequence from a very small amount of tissue like a hair follicle or even a single sperm. you can consider these variants to be "alleles" of a particular site on a chromosome (a "locus"; "loci" in plural). for example, , aaacaaa, aaagaaa, and aaataaa at the same location (call it b) on homologous autosomes in different sperm might be called alleles 1, 2, 3, and 4 of locus b (b1, b2, johns genotype for two loci b and d is bib3 and did3. johns father was bib2 and did4, while his mother was b3b3and d2d3. a. what is (are) the genotype(s) of the parental type sperm john could produce? b. what is (are) the genotype(s) of the recombinant type sperm john could produce? c. in a sample of 100 sperm, 51 of john's sperm were found to be b1, and di, while the remaining 49 sperm were b3 d3. can you conclude whether the b and d loci are linked, or whether they instead assort independently?
