Question Detail
Question
In a normal gametogenesis: a. each egg and sperm cell contains a single sex chromosome b. all sperm cell contain the same kind and amount of DNA c. each egg
Correct Answer
Option A is the correct answer.
Detailed Explanation
The question is incomplete, but option A is correct. In normal gametogenesis, each haploid gamete (egg or sperm) contains a single sex chromosome. In humans, eggs contain one X chromosome, and sperm contain either an X or a Y chromosome. Option B is false because sperm differ in whether they carry an X or Y chromosome, and thus can have slightly different DNA content.
Hint
Gametes are haploid, so they have one copy of each chromosome, including one sex chromosome.
