Question

Why is the number 6 wrong for the HAPLOID chromosome number? I took the total number of chromosomes (DIPLOID number) and divided the answer by 2 as Sapling said that I should, and got the answer of 7. Was that wrong because I counted the sex chromosomes separately instead of as a pair? Then I tried 8 and it was also wrong. I tried 7 and that was wrong too for the HAPLOID chromosome number?

What is the correct answer?

Sapling Learning Imagine a new species of sloth has just been identified after a field study in the rainforest of Australia. The chromosome number of the sloth can be quantified using a colored karyogram. To identify each chromosome, the genome has been tagged with a DNA probe that allows the visualization of each chromosome in a unique color. Using the following karyogram, determine the haploid chromosome number for the new sloth species. Number

Explanation / Answer

In the given karyogram, 16 chromosomes can be observed.
We can see that 1 and 11 are unique (They do not have pairs; Present as a single copy).
So, they could be sex chromosomes.
All the remaining chromosomes are present in single pairs.
So, the diploid chromosome number 2n = 14
Haploid chromosome number n = 14/2 = 7 (6+X or 6+Y)
