Question

which statement describes mendels hypotheses regarding gametes?
a gamete carries two genes for a trait.
a gamete carries one allele for a gene.
a gamete can carry multiple alleles for a trait.
some gametes are dominant and some are recessive.

Explanation:

Mendel's law of segregation states that during gamete formation, the two alleles for a gene separate. Each gamete then receives only one allele for each gene.

• Option A: Incorrect. A gamete does not carry two genes for a trait.
• Option B: Correct. Follows Mendel's law of segregation.
• Option C: Incorrect. A gamete carries one allele for a gene (not multiple alleles for a trait in the sense described here).
• Option D: Incorrect. Gametes do not have the property of being dominant or recessive; alleles are dominant or recessive.

Answer:

B. A gamete carries one allele for a gene.
