AGenes on one chromosome travel together to a gamete
BDominant alleles enter gametes more often than others
CPaired genes segregate equally into the gametes formed
DEach gamete receives both alleles held by the parent
Answer & Solution
Correct answer: C. Paired genes segregate equally into the gametes formed
1. Mendel saw F2 generations splitting 3 dominant to 1 recessive and asked what would produce that.
2. The law of segregation says paired genes segregate equally into gametes.
3. Offspring therefore have an equal likelihood of inheriting either factor.
4. Equal segregation is what lets a Punnett square treat every box as equally likely.
5. A gamete receiving both alleles would make the offspring triploid at that gene, which does not happen.
