Gray seed color in peas is dominant to white. assume that mendel conducted a series of experiments where plants with gray seeds were crossed among themselves, and the following progeny were produced: 302 gray and 98 white. (a) what is the most probable genotype of each parent? (b) based on your answer in (a) above, what genotypic and phenotypic ratios are expected in these progeny? (assume the following symbols: g = gray and g = white.) (a) gg × gg; (b) genotypic = 1: 2: 1, phenotypic = 3: 1 (a) gg × gg; (b) genotypic = 1: 2: 1, phenotypic = 2: 1 (a) gg × gg; (b) genotypic = 1: 2, phenotypic = 3: 1 (a) gg × gg; (b) genotypic = 3: 1, phenotypic = 1: 2: 1 (a) gg × gg; (b) genotypic = 3: 1, phenotypic = 9: 3: 3: 1.

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.

explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
