Correct choices:
- Increase the number of mice bred. — Yes. A larger sample size increases statistical power and reduces sampling error, giving more reliable results.
- Test patterns for future generations. — Yes. Following F2 (and later) generations can confirm inheritance patterns, reveal recessive alleles, segregation, linkage, or unexpected changes.
Not the best choices for "improving the same experiment" (but valid as extensions):
- Examine a different trait within mice. — This changes the question; it might be useful to generalize findings but doesn’t directly improve the original experiment’s design.
- Examine a trait in another species. — That tests generality across taxa but is more an additional study than an improvement to the original experimental design.
