Detailed explanation-1: -A dog is a diploid organism and has 39 pairs of chromosomes (2n = 78), where n = 39 chromosomes from each parent.
Detailed explanation-2: -(See figure below, where meiosis I begins with a diploid (2n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Detailed explanation-3: -If a diploid cell containing 28 chromosomes undergoes meiosis, how many chromosomes will each daughter cell have? EXPLAIN. Each daughter cell will have 14 chromosomes. Meiosis results in haploid gametes, meaning each gamete will have half the original number of chromosomes as the diploid parent cell.
Detailed explanation-4: -At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis).
