Yeast cells exist in two states: haploid and diploid. Haploid yeast belongs to one of two mating types: a, and a. The mating of haploids of opposite mating types produces a diploid.
Two yeast strains were mated: one was red with mating type a, and the other was red with mating type a. Meiosis of the diploids results in the following haploids:
Table showing the genotypes of the haploids (total progeny 100).
How many map units separate the red gene from that for mating type?
