Question
Human gametes are Blank______ and fuse to form a Blank______ zygote.Multiple choice question.diploid; tetraploiddiploid; haploidtetraploid; haploidhaploid; diploid
Solution
The correct answer is "haploid; diploid".
Step 1: Understanding the terms
- Gametes: These are sex cells, produced by organisms that reproduce sexually. In humans, these are the sperm and egg cells.
- Diploid: A cell that contains two complete sets of chromosomes, one from each parent.
- Haploid: A cell that contains a single set of chromosomes.
- Zygote: The cell formed when two gametes (sperm and egg) fuse during fertilization.
Step 2: Applying the terms to the question
- Human gametes (sperm and egg cells) are haploid, meaning they each contain a single set of chromosomes.
- When these gametes fuse during fertilization, they form a zygote.
- The zygote is diploid because it contains two complete sets of chromosomes, one from each parent (one from the sperm and one from the egg).
Therefore, the correct answer is "haploid; diploid".
