Question

How many and what type of chromosomes would be expected in a karyotype of a human male? (1 point) 22 pairs of autosomal chromosomes and 2 Y chromosomes 23 pairs of autosomal chromosomes and 2 Y chromosomes 22 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome 23 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome

Answer 1

The correct answer is

C. 22 pairs of autosomal chromosomes, 1 X chromosomes, and 1 Y chromosomes

I hope this helps.

Answer 2

Remember there are 46 chromosomes in a (normal) human nucleus, which consists of 23 pairs of chromosomes.

Of these, one pair are the sex chromosomes.

In females, the sex chromosomes are XX

In males, the sex chromosomes are XY

So the karyotype of a human male would consist of 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.
