Answer 1

The correct answer is Diploid.

Key Points

In sexually reproducing organisms, the process of fertilization involves the fusion of two gametes: one from the male parent (sperm) and one from the female parent (egg).
Each of these gametes is haploid, meaning they contain one set of chromosomes.
When these gametes fuse during fertilization, they form a zygote which is diploid, containing two sets of chromosomes.
This zygote thus has the same chromosome number as the somatic (non-reproductive) cells of the parent organisms.
In humans, for example, the zygote contains 46 chromosomes – 23 from the mother's egg and 23 from the father's sperm.

Additional Information

Haploid refers to a cell that contains one set of chromosomes, like the egg and sperm cells in humans.
Tetraploid cells contain four sets of chromosomes. Certain plants and animals are naturally tetraploid, which can offer some advantages such as increased size or faster growth.
Polyploidy is a condition where the cells of an organism have more than two paired sets of chromosomes. Polyploid organisms are common in the plant world.
