Sex Determination in Humans
Introduction:
Sex determination in humans is determined by the combination of sex chromosomes inherited from the parents. There are two types of sex chromosomes: X and Y. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
Explanation:
When a sperm fertilizes an egg, it determines the sex of the fetus. Let's consider the scenario where a sperm with 22nd chromosome as Y (22 Y) fertilizes an egg with 22nd chromosome as X (22 X).
Chromosome Combination:
The sperm carries either an X or a Y chromosome, while the egg always carries an X chromosome. Therefore, the possible combinations are:
- If the sperm carrying the Y chromosome fertilizes the egg, the resulting combination will be XY, and the fetus will be male.
- If the sperm carrying the X chromosome fertilizes the egg, the resulting combination will be XX, and the fetus will be female.
Conclusion:
Based on the above explanation, when a sperm with 22 Y fertilizes an egg with 22 X, the resulting fetus will have an XY combination, indicating that it will be a male.
Correct Answer:
The correct answer is option 'A' - Male.
