Diagram the alternate, adjacent-1, and adjacent-2 segregation patterns in anaphase I of meiosis.A diploid (2n) trihybrid individual with the genotype EeFfGg can make eight genetically different gametes. Loci E/e and F/f are on chromosome 1 and locus G/g is on chromosome 2. Explain how a gamete containing the alleles e, f and g may be produced by meiosis. Refer specifically to meiotic events occurring during Prophase I, Metaphase I, Anaphase I and Anaphase II. (NB: remember to refer to the organism above).

- In a diploid organism of genotype A/a; B/b: D/d, the allele pairs are all on different chromosome pairs. The panels in Figure 1 purport to show anaphase in individual cells. Assuming no crossing over, state whether each panel in Figure 1 represents anaphase occurring during meiosis I, meiosis II, mitosis or is impossible for this particular genotype.During the process of Meiosis an individual's alleles for each trait are independently sorted to make unique gametes. A person is heterozygous for the Freckles phenotype (Ff) and also heterozygous for the PTC-tasting phenotype (Tt). This person's genotype for these two traits is represented as FfTt. A) How many unique gametes could be produced by this individual if you consider these two traits? B) List the different allele combinations that could result.Very rarely, one member of a pair of identical (monozygotic) twins will have Turner syndrome (XO) and the other member will be normal (XX).
