In this case, the parental are lengthwise stripes (genotype ls/ls) and plaid stripes (genotype Ps/Ps), the F1 is plaid (100%) and F2 is plaid (75%) and lengthwise (25%). It is a Mendelian inheritance pattern.
<h3>Mendelian inheritance and complete dominance</h3>
Complete dominance occurs when the dominant allele (in this case, the plaid stripe trait) completely masks the recessive allele (lengthwise stripes) in heterozygous individuals.
The cross between tigers having lengthwise stripes (genotype ls/ls) and plaid stripes (genotype Ps/Ps) will produce an F1 100% having the plaid stripes (genotype Ps/ls) trait because this trait is dominant.
In the F2 obtained by crossing heterozygous plaid stripes individuals (genotype Ps/ls), the recessive trait 'lengthwise stripes' will be observed (again) in a proportion of 3:1.
In this case:
- P >> lengthwise stripes x plaid stripes
- F1 >> 100% plaid stripes
- F2 >> plaid stripes (75%) and lengthwise-stripes (25%)

The correct answer is option B (Microevolution)
Microevolution is defined as a change is allele frequencies observed within a population. In contrast to macroevolution it can be observed within a short period of time even within a same generation.
Microevolution can occur due to following reasons:
- Gene flow or Gene migration
- Genetic drift
- Mutation
