1. For one of the monohybrid crosses you performed in this investigation, describe how to use the phenotype ratios to determine the percentage of offspring displaying each trait.
2.Can the genotype for a gray-bodied fly be determined? Why or why not? Describe all of the possible genotypes for a fly with that phenotype.
3.Explain why an organism with a homozygous dominant genotype has the same phenotype as an organism with a heterozygous genotype.
4.What genetic information can be obtained from a Punnett Square? What genetic information cannot be determined from a Punnett Square?

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
