Question

Two dogs–a boxer and a poodle–were the first to have their entire genomes sequenced. The dog genome contains 2.8 billion2.8 billion base pairs across 3939 pairs of chromosomes. They have 19,00019,000 protein-coding genes, most of them with close counterparts in other mammals, including humans. What is the total number of chromosomes in a dog?

Answer 1

78 chromosomes

Step-by-step explanation:

Since the number of chromosomes in a dog are diploid, we have 2n chromosomes where n = number of chromosome pairs.

Since n = 39.

The number of chromosomes is 2n = 2 × 39 = 78 chromosomes

So, a dog has 78 chromosomes.
