Question

which statement summarizes the law of segregation?
○ gametes are passed in pairs, groups, or sets.
○ traits that are dominant mask traits that are recessive.
○ gametes carry one allele for each trait.
○ traits are passed independently of one another.

Explanation:

The law of segregation (Mendel's first law) states that during gamete formation, the two alleles of a gene segregate so that each gamete carries only one allele for each trait. Let's analyze the options:

• "Gametes are passed in pairs, groups, or sets" is incorrect as gametes are haploid and carry one allele per trait, not passed in pairs/sets for alleles of a single trait.
• "Traits that are dominant mask traits that are recessive" describes the law of dominance, not segregation.
• "Gametes carry one allele for each trait" matches the law of segregation.
• "Traits are passed independently of one another" describes the law of independent assortment, not segregation.

Answer:

C. Gametes carry one allele for each trait (assuming the options are labeled A, B, C, D with this as option C; if original labels differ, adjust to the correct option text with its identifier)
