A mature female wolf, with 78 diploid chromosomes in each somatic cell, produces haploid oocytes (egg cells) containing how many chromosomes per cell? 1 sex-determining chromosome (Y) and 38 autosomes 2 sex-determining chromosomes (XX) and 76 autosomes 1 sex-determining chromosome (X) and 39 autosomes 2 sex-determining chromosomes (XY) and 76 autosomes 1 sex-determining chromosome (X) and 38 autosomesWhich of the statements is FALSE? Somatic cells are diploid in diploid organisms. Gametes are produced from meiosis by germline cells. Somatic cells are capable of both mitosis and meiosis. Somatic cells and gametes from the same organism have different chromosomal complements.
