Which of the following cell types could have 22 autosomes and a Y chromosome?
A
Sperm
B
Egg
C
Female somatic cell
D
Male somatic cell
Explanation: 

Detailed explanation-1: -So the correct option is ‘sperm cell’.

Detailed explanation-2: -Twenty-two autosomes and Y chromosomes are present in the sperm. The sperm is the male gamete that fuses with the female ovum and donates the Y chromosome to the offspring. The sperm is the gamete that contains the Y chromosomes.

Detailed explanation-3: -The male somatic cells comprise 22 autosomes and the ‘XY’ chromosome.

Detailed explanation-4: -Human sperm (and eggs) are in the haploid state, meaning that only have one copy of each chromosome, or 22 autosomes and one sex chromosome (either X or Y).

Detailed explanation-5: -Egg cells are haploid gametes of females, which means they have one-half set of chromosomes. Thus, they have 22 autosomes and an X-chromosome for a total of 23 chromosomes total, half of the 46 chromosomes in a complete somatic cell.
