Answer 1

The correct answer is 50%.

When a long-tailed mouse that is heterozygous (Ll) mates with a short-tailed mouse (ll), there is a 50% chance that the offspring will inherit the dominant long tail allele (L) from the long-tailed parent and have long tails (Ll), and a 50% chance that they will inherit the recessive short tail allele (l) from the short-tailed parent and have short tails (ll).
