Two haploid yeast with the genotypes HIS4 LEU2 LYS2 and his4 leu2 lys2 were mated to produce diploid yeast. Next, the resulting diploid yeast went through meiosis and formed haploid spores. Read the 4 statements below. For each statement, either put “yes” if you agree with it or put “no” if you don’t. Explain your logic. yes/no 1. Half of the spores will be His+ and half will be His- 2. Half of the spores will be Leu+ and half will be Leu- 3. Half of the spores will be Lys+ and half will be Lys- 4. Half of the spores will be His+ Leu+ Lys+ and half will be His- Leu- Lys-

Two yeast strains were mated. One was red with mating type A the other was red+ with mating type B. The resulting diploids were induced to undergo meiosis and the meiotic products of the diploids were as follows: 41 red+ B 43 red A 10 red+ A 6 red B How many map units separate the RED gene from the mating type gene? (just write the number, no units please)

Shown below are photomicrographs of Rhoeo tradescantia cells undergoing meiosis. Answer the following question for each of the photomicrographs: Identify the cytogenetic abnormality observed (ex. ring, chain, laggard, bridge).
