The normal chromosome complement in males is?

Correct option is D

Sol. Human males normally have 46 chromosomes, including one X and one Y chromosome (46XY). The 46 chromosomes include 22 pairs of autosomes and one pair of sex chromosomes that determine male biological sex.
Explanation of each option:
· (a) 45XY – Indicates one missing chromosome, which may lead to chromosomal disorders like Turner syndrome.
· (b) 46XX – This is the typical female chromosome pattern, not male.
· (c) 44XY – Represents only 22 pairs of autosomes and sex chromosomes, missing two total chromosomes.
· (d) 46XY – Correct. This is the standard male karyotype with 23 pairs of chromosomes.
