Yellow spotted coloration in certain plants shows up randomly distributed in offspring, no matter what parental crosses are made. there is also a random distribution of the trait between male and female plants. assuming that one gene is responsible for the trait, which statement could be true about this gene? '
a. it could be a sex-limited trait b. it could be a dominant trait c. it could be carried by a chloroplast chromosome. d. it could be carried by a sex chromosome.

C. It could be carried by a chloroplast chromosome.

Anything is transmitted by genes or chromosome.

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.
