Answer:
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.
Explanation:
For example, pea plants are either tall or short, which is an easy trait to observe, with that being said pea plants grow quickly, so he could complete many experiments in a short period of time.
Answer;
Division of Labor
Explanation;
Eusocial animals express complex behaviors, like group decision-making.
Eusocial animals share several characteristics which includes: adults live in groups, cooperative care of juveniles (individuals care for brood that is not their own), reproductive division of labor (not all individuals get to reproduce), and overlap of generations.
For example; Ants, termites and many species of bees and wasps form tightly integrated social groups in which permanently nonreproducing workers help rear the offspring of a few fertile individuals, the queens and males.
With stabilizing selection, the phenotype for a trait does not influence survival. Stabilizing selection reduces the amount of variation in a trait.
Disruptive selection increases the amount of variation in a trait. With stabilizing selection, extreme individuals have high biological fitness.
