In a diploid set of chromosomes, one member of each pair of homologous chromosomes is derived from the father (paternal), and the other comes from the mother (maternal).
.......If 2n = 6, what is the probability of obtaining a gamete in which all the chromosomes are paternal ones?

Meiosis consists of 2 nuclear divisions that reduce the # of chromosomes to the haploid # (n) in preparing for sexual reproduction. Not Diploid (2n).
The fertilization of the haploid cells, sperm and ova, is the diploid cell (zygote) which gives a 50% chance of daughter cells being maternal or paternal.
# of possible combinations = 2 to the nth power (2 ^n)
so, if 2n=6, then n=3 and there is 2 ^3 = 8 number of combinations.

theres a 1/6 chance of getting the paternal dna so 1/6*1/6*1/6= about .5%

meiosis is Haploid not Diploid, Dipliod is for Mitosis which is different. if 2n=6 then n=3

That all depends on the distribution of sex chromosome y, which determines male sex.
