If an organism has 11 pairs of chromosomes, which mathematical equation will calculate the number of combinations in which homologous chromosomes can orientate themselves during meiosis I?
The calculations shown in the choices are all mathematically correct.
211 = 2 048 combinations
222 = 484 combinations
222 = 4 194 304 combinations
112 = 121 combinations
Which is the best explanation for the term reduction division as it relates to meiosis?
The mass of DNA in each cell has been reduced.
The overall amount of DNA has been reduced during meiosis.
The chromosome number has been reduced.
DNA is chemically reduced during the process of meiosis.
