Question

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

Answer 1

Answer:

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.
