WebRelative to other members of Canidae, these species have high diploid complements (2n greater than 64) consisting of largely acrocentric chromosomes. They show a considerable degree of chromosome homoeology, but relative to the grey wolf, each species is either missing chromosomes or has unique chromosomal additions and rearrangements. WebExpert Answer. Since the diploid chromosome number in case of dog is 78 (2n = 78), Halpoid number of chromosomes = n = 78/2 = 39 Number of different arrangements of the maternal total number of l and paternal possible during metaphase I = 2n Here n = 39 So the tot ….
