All gametes contain ______ allele for each gene.
(A) two
(B) four
(C) one
(D) three
Answer (2)
Gametes contain one allele for each gene, as they are produced through meiosis, which reduces the chromosome number by half. This means that during gamete formation, only one allele from each homologous pair is passed on. Therefore, the correct answer is (C) one.

In biological terms, gametes are the reproductive cells used during sexual reproduction to produce a new organism or offspring. In humans and many other organisms, the main types of gametes are sperm in males and eggs (or ova) in females.
Each gamete contains one allele for each gene. This is because gametes are haploid cells, meaning they carry half the genetic material of a normal diploid cell. During the process of meiosis, which is how gametes are formed, the number of chromosomes is reduced by half. This ensures that when two gametes unite during fertilization, the resulting offspring have the proper amount of genetic material.
Therefore, the correct answer to the question "All gametes contain ______ allele for each gene" is:
(C) one
The concept can be a bit tricky, but it helps maintain genetic diversity and ensures the accurate transmission of genetic information from parents to offspring.
