Answer:
39 daughter chromosomes
Explanation:
This question is describing the MITOTIC process, which involves the synthesis of two daughter cells from one parent cell. In mitosis, sister chromatids, which forms a chromosome, separates at their centromere to become individual chromosomes in their respective daughter cells.
N.B: Mitosis produces two daughter cells which are identical in chromosome number.
In this case, a dog is said to have 39 chromosomes in its diploid cell. Since two chromatids make up one chromosome, 78 chromatids will be found in the dog cell. The 78 sister chromatids that form 39 chromosomes will each separate at their centromere to form 39 daughter chromosomes in each daughter dog cell.
