Question

5 Draw homologous chromosomes (replicated) for an individual heterozygous at both the A and B loci which are 10 map units apart and where the dominant alleles are carried in cis (don't put the centromere between the loci) In the absence of crossing over what kinds of eggs can she produce and in what frequency? In the presence of crossing over what kinds of eggs can she produce and in what frequency? Draw the cross-over event on vour chromosome. Add a C locus 20 map units to the right of B (again, don't let the centromere be between loci) Make the individual heterozygous at C, with the dominant allele in cis to the other dominant alleles. In the absence of crossing over what kinds of eggs can she produce and in what frequency? In the presence of crossing over what kinds of eggs can she produce and in what frequency (remember that the probability of two independent events occurring simultaneously is the product of their independent probabilities) 6. Repeat question 5 for an individual where A and b are on one chromosome and a and B are on the homologue (Ab/aB). When you add the C locus put the dominant allele (C) with Ab and the recessive allele (c) with aB (AbC/aBc) G6PD -5 map units hem. A 3 map units--- rcb gcb 7. The map for G6PD, hemophilia A and the color blindness genes is given above. If a mother has the genotype G6PDA on the same chromosome as the gene for color blindness (rcb) and the other chromosome has the G6PDB and the normal gene for color vision. What are the chances that a son who is colorblind has the B form of G6PD?
