Document Summary
Suggested readings and example questions for lecture 7 and 8 for the fourth edition of the textbook. You should be able to answer the following problems in chapter 5. Problems 38, 39, 40 are tough problems that you would not expect on the exam. Example exam problems: a neurospora arg2 mutant haploid (requires arginine for growth) is crossed with a leu5 mutant haploid (requires leucine for growth). The genes arg2 and leu5 are: unlinked, 50 map units (mu) apart, 31 mu apart, 16 mu apart, 1 mu apart, using the tetrads dissected in question 1. You have created a diploid in which one homolog of chromosome 2 carries a let1 mutant allele (this chromosome is. Let2+) and the other homolog of chromosome 2 carries a let2 mutant allele (this chromosome is let1+). The two loci are 10 centimorgans (cm) apart. 1 ura3 and the other 50% are 1 ura3 : 3 ura3. You found by accident that one of your.
