1)What are the gametic consequences of a lack of
sister chromatid separation (non disjunction ) in meiosis 2 of the
cell division. How does this result compare to non disjunction in
meiosis 1? draw pictures of the gametes to illustrate
2) what are the gametic consequences of a lack of cytokinesis following the first or second meiotic division ? draw pictures of the gametes to illustrate.

12:52 PM Mon Apr 13 78% B06 Draw a diagram to represent the equational division of meiosis for a diploid organism with three heterologous chromosomes. One acrocentric, one metacentric and one telocentric. The diagram should show the chromosomes as you'd expect to see them during metaphase. The organism is trihybrid and heterozygous for dominant and recessive alleles at three different loci. Locus A is on the telocentric chromosome. Locus B is on the metacentric chromosome....
