Answer:the answer is B hope this help
Explanation:
Plasticity is most adaptive when the environment change <u>Slowly and predictably </u>throughout an organism's life.
The ability of individual genotypes to create various phenotypes when exposed to various environmental situations is known as phenotypic plasticity. Here, the emphasis is on the role of plasticity in evolution rather than the evolution of plasticity itself, i.e., the evolution of phenotypic traits and organismal variety through plasticity. Phenotypic plasticity is a crucial characteristic of developmental systems that enables the organism to deal with environmental variability and/or unpredictability, although its significance for adaptive evolution is still debated.

Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
