60

Explanation:
Detailed explanation-1: -Cows have 60. Cats have 38. Fruit flies have 8. Humans have 46.
Detailed explanation-2: -The total number of chromosomes is referred to as the chromosome number. The haploid number in humans is given as 2n=46, n = 23, this is because the haploid human cells possess one set of 23 chromosomes – 22 sets of autosomal chromosomes (non-sex chromosomes) and 1 set of sex chromosomes.
Detailed explanation-3: -The haploid cells contain half the number of chromosomes as the diploid cells. Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes.
