Which statement describes Mendel’s hypotheses regarding gametes? A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.

The correct answer is B. A gamete carries one allele for a gene.

Explanation:

Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.

According to the Law of segregation given by Gregor Mendel-

During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.

Thus, option B) is the right answer.
