Question

below is a karyotype of a sheep. how many chromosomes do sheep have?

Explanation:

Step1: Count the number of chromosome pairs

There are 26 pairs of autosomes (numbered 1 - 26) and 1 pair of sex chromosomes (X and Y). So in total, there are \(26 + 1=27\) pairs of chromosomes.

Step2: Calculate the total number of chromosomes

Since each pair contains 2 chromosomes, the total number of chromosomes is \(27\times2 = 54\)

Answer:

54
