Question

1. why are animal gametes haploid?

○ gametes have two copies of each chromosome.
○ haploid egg and sperm cells combine to create a diploid individual.
○ gametes have one copy of each chromosome to create a haploid individual.
○ gametes are developing embryos that develop into haploid adults.

Explanation:

Haploid cells have one copy of each chromosome. Animal gametes (egg and sperm) are haploid so that when they fuse during fertilization, their genetic material combines to form a diploid zygote, which develops into a diploid adult animal. The other options are incorrect: the first describes diploid cells, the third incorrectly states gametes create a haploid individual, and the fourth misidentifies gametes as embryos.

Answer:

B. Haploid egg and sperm cells combine to create a diploid individual.
