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

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
