Question

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes, demonstrate your understanding of mitosis and meiosis by answering the following questions: a) The diploid (2n) number for this cell is The haploid (In) number is b) Draw what this cell would look like in metaphase of mitosis showing the chromosomes and alleles as well as microtubules. (See above for chromosome and allele descriptions.) c) Considering independent assortment, but ignoring crossing over, draw two cells in anaphase I of meiosis showing two distinct ways the chromosomes may align. Use clearly drawn and labeled chromosomes and show the appropriate alleles on every chromatid. Your two examples should result in genetically distinct gametes should the cells continue through meiosis
