Diploid Sordaria cells that are heterozygous for alleles A (light spore color) and a (dark spore color) undergo meiosis and then mitosis to produce 8 ascospores in an ascus sack. You analyze the spore patterns in several thousand asci. Explain why you find there are approximately equal numbers of asci with a 4:4 pattern of light spores on top vrs dark spores on top. What does this data tell you about the behavior of homologous chromosomes during meiosis
