A human cell that contains 22 autosomes and a Y chromosome must be(A) a zygote.
(B) a somatic cell of a male.
(C) a somatic cell of a female.
(D) a sperm cell.
(E) an egg cell

Answers

Answer 1
Answer: Well it can't be C because the DNA of female cells do not have any Y sex chromosomes. It also can't be E because of that same reason (the egg is made by the female, so it can only contain her genes).It can't be A because zygotes are diploid (because the egg and sperm, both haploid with 23 chromosomes, fuse together to double the amount of chromosomes), so a zygote would have to have 46 chromosomes, not 23 with 22 being autosomal and 1 being allosomal/sexual like the question states. And finally, it can't be B because somatic cells are also diploid and have 46 chromosomes. Another clue it can't be B is that the question states it has only a Y chromosome, which means the cell can't be diploid because a diploid cell has two allosomal chromosomes, either XX or XY.
Answer 2
Answer:

Final answer:

A human cell with 22 autosomes and a Y chromosome is a male sperm cell. Sperm and egg cells contain 23 chromosomes, including one sex chromosome, while other cells typically have 46 chromosomes.

Explanation:

A human cell that contains 22 autosomes and a Y chromosome is (D) a sperm cell. Human cells are normally diploid, meaning they contain 46 chromosomes: 22 pairs of autosomes and a pair of sex chromosomes. Somatic cells (both male and female) have a total of 46 chromosomes, while a zygote, the cell formed after the fusion of an egg and a sperm, is also diploid. However, sperm and egg cells, which are haploid, carry only 23 chromosomes: 22 autosomes and either an X (in the case of an egg cell or a male sperm cell) or a Y (in the case of a male sperm cell) chromosome.
