A dog has 78 chromosomes in its body cells. What is the diploid number?
A
78
B
39
C
1
D
100
Explanation: 

Detailed explanation-1: -So, if there are a total of 78 chromosomes then half of its number (half of 78) is 39 chromosomes are present in the female gamete or egg cell. So, the egg cell will have 39 numbers of chromosomes. Therefore, the answer is 39 chromosomes would be present in its egg cell.

Detailed explanation-2: -Complete answer: Dogs have 78 Chromosomes in their diploid cells. In simply diploid cells (2n) means two sets of chromosomes are there in the cell. Haploid (n) cells mean only one cell is present.

Detailed explanation-3: -Dogs have 78 chromosomes in their diploid cells. How many chromosomes are in their haploid cells? 2n = 78 so n = 78/2 = 39 Dogs have 39 chromosomes in their haploid cells.

Detailed explanation-4: -A dog (Canis familiaris) has 78 diploid number of chromosomes.

Detailed explanation-5: -Each species has a set number of chromosomes arranged in pairs within each cell, but the number of chromosomes can differ between species. Humans have 46 chromosomes (23 pairs), dogs have 78 chromosomes (39 pairs), cats have 38 chromosomes (19 pairs), and so on.
