To determine how many chromosomal configurations can occur following meiosis I if an organism has 6 total chromosomes, use the equation where n

2^n where n is the haploid number of chromosome (3)

Explanation:

According to the question, this organism has total chromosomes of 6, which means its gametes after meiosis will have a chromosome number of 3. However, a phenomenon called CROSSING-OVER occurs in meiosis I that increases the chance of genetic diversity/variation among species. This process of crossing-over causes chromosomes to be rearranged in a way different from the parents.

However, the possible number of different combinations of chromosomes in the resulting gametes after meiosis can be found using the simple formula 2^n where n is the haploid number of chromosome. In this case, the haploid number is 3, since the total chromosomes are 6. Hence, 2^3 = 8. It can be said that the particular organism in the question can possibly have 8 different chromosomal combinations in its gamete.

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.
