The genotype of the cell above is AaBbCc, where the A and B loci are on the large chromosome and the C locus is on the small chromosome. Assume this cell was taken from an F1 organism that resulted from the cross of two true-breeding parents of the following genotypes.
Parent 1: AAbbCC and Parent 2: aaBBcc
b) Draw and align the chromosomes as they would appear in metaphase of mitosis in an F1 cell. Include the A, a, B, b, C, and c alleles on the drawing.
Now consider Meiosis.
c) Draw the two possible arrangements of chromosomes on the figures below labeled arrangement 1 and 2 as they could appear in metaphase of Meiosis I. Make sure to include the alleles (A, a, B, b, C, and c) on the drawing and assume no crossing over.
d) Given your drawings for c), draw the chromosomes in each of the two products resulting fromMeiosis I. Again, make sure to include the alleles (A, a, B, b, C, and c) on the drawing and assume no crossing over.
Arrangement 1
Metaphase of meiosis I Product 1 of meiosis I Product 2 of meiosis I Arrangement 2
Metaphase of meiosis I Product 1 of meiosis I Product 2 of meiosis I
e) What would be the genotypes of the gametes produced from arrangement 1?
f) What would be the genotypes of the gametes produced from arrangement 2?
g) Which loci, (A & B) or (A & C) are obeying Mendel's law of independent assortment?
